Python string formatting
Here, we will see python string formatting with an example.
The Python string format() method allows the formatting of the selected parts of a string. We use format to make sure that the string will display as expected.
To control such value, add a placeholder curly bracket {} in the text and then run the values through the format() method.
Example:
roll = 101
msg = "The roll start from {} "
print(msg.format(roll))To get the output, I have used print(msg.format(roll)). You can refer to the below screenshot for the output.
This is how we can do string formatting in Python.

Python string formatting multiple values
Now, we will see python string formatting multiple values.
In this example, we will use multiple values in order to add multiple values to the format() method we just have to add a placeholder curly bracket {} in the text and then run the values through the format() method.
Example:
roll = 1
sub_code = 121
msg = "The roll {} has taken subject math and the code is {}."
print(msg.format(roll, sub_code))To get the output, I have used print(msg.format(roll, sub_code)). You can refer to the below screenshot for the output.

Python string formatting padding
Lets see python string formatting padding.
Python string can be formatted in a similar way with format(). Here, string padding with left alignment is done, and the value can be padded to a specific length. The padding character can be space or a specified character.
Example:
print("{:10}".format("Welcome"))To get the output, I have used print(“{:10}”.format(“Welcome”)). You can refer to the below screenshot for the output of string formatting padding in Python.

Python string formatting padding with right alignment
Now, we will see python string formatting padding with right alignment.
In python string formatting padding with right alignment, we will use “>” for string padding in right to remaining places.
Example:
print("{:>8}".format("Hello"))To get the output, I have used print(“{:>8}”.format(“Hello”)). You can refer to the below screenshot for the output.

Python string formatting padding with center alignment
Here, we will see python string formatting padding with center alignment.
To get string formatting padding with center alignment we will use “^” for the center aligned to the remaining places.
Example:
print("{:^10}".format("Python"))To get the output, I have used print(“{:^10}”.format(“Python”)). You can refer to the below screenshot for the output.
This is how to do Python string formatting padding with center alignment.

Python string formatting padding with center alignment and * padding character
Now, we will see string formatting padding with center alignment and * padding character.
To get string formatting padding with center alignment and * padding character we will use “*” for padding the remaining space and “^” is used for the center aligned.
Example:
print("{:*^10}".format("Guides"))To get the output, I have used print(“{:*^10}”.format(“Guides”)). You can refer to the below screenshot for the output.

Python string formatting using f
Here, we will see python string formatting using f.
To create a string formatting using f, we have prefix the string with the letter “f”. The string itself can be formatted in the same way like we used str.format(). F-string is a convenient way for formatting.
Example:
value = 'Python'
print(f"Hello, Welcome to {value} tutorial {value} is very interesting.")To get the output, I have used print(f”Hello, Welcome to {value} tutorial {value} is very interesting.”). You can refer to the below screenshot for the output.
This is how to do string formatting using f in Python.

Python string formatting float
Now, we will see python string formatting float.
In the python string formatting float, we have used “{ }” as a variable inside the formatting brackets. In this example, the precision variable control how many decimal places to show.
pi = 3.1415926
precision = 2
print( "{:.{}f}".format( pi, precision ))To get the output, I have used print(“{:.{}f}”.format( pi, precision)). You can refer to the below screenshot for the output.

Python string format methods
Now, we will see python string format methods.
The format() method formats the specified value and insert them inside the string placeholder. The placeholder is defined by using curly brackets “{ }” and the price is fixed, with two decimal format.
val = "Its only {price:.2f} Rupees!"
print(val.format(price = 84))To get the output, I have used print(val.format(price = 84)). You can refer to the below screenshot for the output.
Python string formatting decimal places
Here, we will see python string formatting decimal places.
In python string formatting decimal places, we have used “{:.3f}” to format a float to 3 decimal places and by using the format() it will get formatted.
Example:
print("{:.3f}".format(2.123456))To get the output, I have used print(“{:.3f}”.format(2.123456)). You can refer to the below screenshot for the output.
This is how to do string formatting decimal places in Python.

Python string formatting integer
Now, we will see python string formatting integer.
In string formatting integer, we will use “d” which is used for integer argument. The placeholder is defined by using curly brackets “{ }”.
Example:
print("My marks is {:d} in maths".format(80))To get the output, I have used print(“My marks is {:d} in maths”.format(80)). You can refer to the below screenshot for the output.
Python string uppercase
Here is another Python string formatting example.
- Using the Python string upper() method we can convert all lowercase characters of a string into uppercase.
- To convert any string in uppercase we have built-in upper() method in Python which will convert lowercase to uppercase.
- The function can take any lowercase string as an input and it can produce a string in uppercase as an output.
Example:
- First of all, We need to take a string value. In the below python code, You can see, I have taken the value as “welcome to python”.
- Now print the “msg.upper()” and it will return the string in uppercase letter.
Python string uppercase Code
Below represents the python code for string uppercase.
msg = "welcome to python"
print(msg.upper())- After writing the above Python code (string uppercase), Ones you will print “msg.uppercase()” then the output will appear as a “WELCOME TO PYTHON” which will return a uppercase string as an output. Also, you can refer to the below screenshot.
This is how to convert a string to uppercase in Python.
Python capitalize each word in a string
In python, to capitalize each word in a string we will use the built-in method upper() to capitalize all the letters in the string.
Example:
my_string = 'python guides'
print(my_string.upper())After writing the above Python code (python capitalize each word in a string), Ones you will print “my_string.upper()” then the output will appear ” PYTHON GUIDES “. Here, the string.upper() is used to capitalize each word in the string. Also, you can refer to the below screenshot to capitalize each word in a string.
This is another Python string formatting example, where we saw how to capitalize each word in a string in Python.
