## Python generate random number

Let us see various ways to **generate random number in Python**. We will discuss different ways to **generate random numbers in Python**.

In this example, I have imported random module,**random()** returns the random floating value.

Example:

```
import random
random_number = random.random()
print(random_number)
```

This way, we can **create a single random number in Python**.

### Python random number between 0 and 1

Now we can see **how to get a random number between 0 to 1** in python

To get any random number we have to first import **random** module. **random.uniform()**is used to get a random number, The uniform() returns random floating-point numbers between the two given numbers.

Example:

```
import random
number = random.uniform(0,1)
print(number)
```

Below screenshot shows the output:

### Python random number integers in the range

Here we can see **how to get a random number integers in the range** in python,

In this example we can see how to **get a random number when the range** is given, Here I used the **randint()** method which returns an integer number from the given range.in this example, the range is from 0 to 10.

Example:

```
import random
random_number = random.randint(0, 9)
print(random_number)
```

Below screenshot shows the output:

### Python random numbers between 1 and 10

Here we can see **how to get a random numbers between 1 and 10** in python

In this example,I have used **randint() **which returns a random number when range is specified.

Example:

```
import random
print(random.randint(1,10))
```

Below screenshot shows the output:

### Python random number seed

We can use the **Python Seed function** to initialize a random number in Python. By default, it will create a random number by using the current time of the system.

To get customize the start number of the random number generator, we can use **seed() **function

Here we can see **how to generate a random number using seed() function** in python.

Example:

```
import random
random.seed(15)
print(random.random())
```

Below screenshot shows the output:

### Python random number of choice

In this, we can see **how to get a random number from the specified sequence of list or string** in python

In this example, **random.choice() **is used, which returns a random number from the specified Python list.

Example:

```
import random
numberList = [1,22,58,14,25,24,]
print( random.choice(numberList))
```

Below screenshot shows the output:

### Python random integer number multiple of n

Now we can see **how to get a random integer number multiple of n** in Python.

Here we can generate a random number which is multiple of 4 from the range 4 to 200.and used print(num) to print the random number.

Example:

```
import random
num = random.randrange(4, 200, 4)
print(num)
```

Below screenshot shows the output:

### Python random number shuffle

In this we can see **how to get a random number using shuffle()** in python.

In this example, some numbers are assigned to a list number and **random.shuffle() **is used to get random shuffle number from the list.

The **shuffle()** method takes a sequence of numbers in the list and reorganizes the order of numbers in the list randomly.

Example:

```
import random
number = ["1","5","2","3"]
random.shuffle(number)
print(number)
```

Below screenshot shows the output:

### Python random number between two floats

Now we can see **how to get a random numbers between two floats** in python

In this example, we have to import a random module, and** random.uniform()** function is used to get a random number.

The **uniform() returns random floating-point numbers between the two given floating numbers**.

Example:

```
import random
x = random.uniform(0.5, 1.5)
print(x)
```

Below screenshot shows the output:

### Python random number with n digits

Now we can see** how to get a random number with n digits** in python.

To get a random number with n digits **random.radint() **is used which returns the random number of length of two given digits. The length of the random number will be equal to the length of two given numbers.

Example:

```
import random
random_number = random.randint(1000, 2000)
print(random_number)
```

Below screenshot shows the output:

### Python random number without repeating

In this we can see **how to get a list of random numbers without repeating** in python.

In this example, I have used Python **random.sample()** function which generates the unique random number within the given range of numbers.

Example:

```
import random
list = random.sample(range(0, 10), 10)
print(list)
```

Below screenshot shows the output:

This is how we can **generate a random number in Python using random.sample()**.

## Python random 10 digit number

Here we can see how to **generate a random 10 digit number in Python**. To get a random number of specified lengths we should set maximum and minimum values.

In this example, I have imported a module random and to get a random number we should generate N and assign minimum – **minimum = pow(10, N-1) **and maximum – **maximum = pow(10, N) – 1** and then return a random number of length as given in the argument.

Example:

```
import random
def randomnumber(N):
minimum = pow(10, N-1)
maximum = pow(10, N) - 1
return random.randint(minimum, maximum)
print(randomnumber(10))
```

Below screenshot shows the output:

This is how we can **generate a random 10 digit number in Python** very easily.

## Python random number using sample()

Now we can see how to **generate random number using sample()**.

In this example, I have imported random module and sample module from random, I have taken a list as numbers and print () contains a **sample()**, a** list**, and the **size of the list.** The **sample()** returns the random list from the specified list.

Example:

```
from random import sample
numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9]
print(sample(numbers,5))
```

Below screenshot shows the output:

## Python generate random string

Now, let us see **how to generate random string in Python**.

In this example, I have imported two modules they are random and string and to get a random string

Call **string. ascii** is initialized to get a constant string, string.ascii_uppercase gives only uppercase letters. and choice() returns randomly selected elements from any sequence.

Example:

```
import random
import string
letters = string.ascii_uppercase
print ( ''.join(random.choice(letters)))
```

Below screenshot shows the output:

### Python random string of length

Here we can see **how a random string of specified length** in python

In this example, I have used **length_of_string = 4**, It is the length of string function returns the number of character in the input string. and also the **range()** function is used to get the range of length of the string,

And **choice()** returns randomly selected elements from any sequence.

Example:

```
import random
import string
length_of_string = 4
letters = string.ascii_uppercase
random_string = ""
for number in range(length_of_string):
random_string += random.choice(letters)
print(random_string)
```

Below screenshot shows the output:

### Python random string of list

Here we can see **how to get a random string from a given list **in python

In this example, a list is given and a random string is generated from that string itself. as above showed here also use the same random. choice() which returns randomly selected elements from any sequence.

Example:

```
import random
import string
print(random.choice(['mango', 'orange', 'apple']))
```

Below screenshot shows the output:

### Python random string of letters and numbers

In this we can see **how to get random string of both letters and numbers in python**

In this example **string join()** is used which joins all the items from the string.

”.join(random.choices(string.ascii_uppercase + string.digits, k = N) this method joins random alphabets and digits.

Example:

```
import string
import random
N = 5
res = ''.join(random.choices(string.ascii_uppercase + string.digits, k = N))
print("The random string : " + str(res))
```

Below screenshot shows the output:

### Python random string with special character

Here we can see **how to get a random string with special chracter** in python

This example is similar to a random string of letters and numbers string punctuation is also added to it to get the special character in the string and **string join() **is used which joins all the items from the string.

```
import random
import string
def randomStringwithDigitsAndSymbols(stringLength=4):
special_characters = string.ascii_letters + string.digits + string.punctuation
return ''.join(random.choice(special_characters)
for i in range(stringLength))
print (randomStringwithDigitsAndSymbols())
print (randomStringwithDigitsAndSymbols())
print (randomStringwithDigitsAndSymbols())
```

Below screenshot shows the output:

### Python random string from alphabets

Here we can see **how to get random string only from alphabets **in python,

In this example length of the string is used, and also **string join() **is used which joins all the items from the string. **range () **which returns the length range of the string.

Example:

```
import random
import string
string_length = 8
upper_case_alphabet = string.ascii_letters
lower_case_alphabet = string.ascii_letters
random_upper_letter = random.choice(lower_case_alphabet)
random_lower_letter = random.choice(upper_case_alphabet)
print(''.join(random.choice(random_upper_letter+random_lower_letter) for i in range(string_length)))
```

Below screenshot shows the output:
