Remove first character from string python

Now, we will see how to remove first character from string in Python. We can use replace() function for removing the character with empty string as the second argument, and then the character is removed.


Example:

my_string = 'Welcome'
print(my_string.replace('W', '')

After writing the above code (remove the first character from string python), Ones you will print “ my_string.replace() ” then the output will appear as an “ elcome ”. Here, the first character is ‘W’ which is replaced with an empty string in python.

You can refer to the below screenshot to remove the first character from string python

Remove n character from string python

Now, we will see how to remove n character from string in Python. We can use the string slicing ” [n:] ” where n is used for the amount of character to remove from the string.

Example:

my_string = 'Welcome'
remove = my_string[3:]
print(remove)

After writing the above code (remove n character from string python), Ones you will print “ remove ” then the output will appear as a “ come ”. Here, n is 3 so the first 3 characters are removed from the string python.

You can refer to the below screenshot to remove n character from string python

This is how we can remove n character from string python.

Remove newline from string python

In python, to remove newline from string we can use replace() function for removing the ” \n ” from the string and it will remove all newline.

Example:

my_string = 'Welcome\nto\n2020'
print(my_string.replace('\n', ''))

After writing the above code (remove the newline from string python), Ones you will print “ my_string.replace() ” then the output will appear as a “ Welcometo2020 ”. Here, ” \n ” is removed with the empty string as a second argument, and the newline is removed from the string.

You can refer to the below screenshot to remove newline from string python

Remove specified number of times in python

In python, to remove a specified number of times we can use replace() function with 3 parameters to specify the number of times replacement should take place in a string.

Example:

my_string = 'Welcome'
print(my_string.replace('e', 'E', 2))

After writing the above code (remove the specified number of times in python), Ones you will print “ my_string.replace() ” then the output will appear as a “ WElcomE ”. Here, ” e ” is removed with ‘ E ‘ as a second argument and the third argument is the number of times replacement takes place.

You can refer to the below screenshot to remove specified number of times in python

This is how we can remove specified number of times in python.

Python replace multiple characters in a string

In python, to replace multiple characters in a string we will use str.replace() to replace characters and it will create a new string with the replaced characters.

Example:

my_string = "Sixty"
remove = ['t', 'y']
for value in remove:
my_string = my_string.replace(value, '')
print(my_string)

After writing the above code (python replace multiple characters in a string), Ones you will print “ my_string ” then the output will appear as a “ Six ”. Here, ” t ” and ” y ” old value are replaced with new which is an empty string.

You can refer to the below screenshot python replace multiple characters in a string

Remove string from string python

In python, to remove a string from the string we will use a str.replace() method for removing the string from string python and it will create a new string.

Example:

my_string = "Sixty people arrived in the hostel"
remove = ['arrived']
for value in remove:
my_string = my_string.replace(value, '')
print(my_string)

After writing the above code (remove string from string python), Ones you will print “ my_string ” then the output will appear as a “ Sixty people in the hotel ”. Here, ” arrived ” is removed with the empty string.

You can refer to the below screenshot python remove string from string python

How to remove punctuation from a string python

In python, to remove punctuation from a string python we will use for loop to remove all punctuation from the string python.

Example:

punctuation = '''!/[email protected]#$%^&*_~()-[]{};:'"\,<>.'''
my_string = "Hello!? World!!"
remove_punct = ""
for character in my_string:
if character not in punctuation:
remove_punct = remove_punct + character
print(remove_punct)

After writing the above code (how to remove punctuation from a string python), Ones you will print “ remove_punct ” then the output will appear as a “ Hello World ”. Here, we will check each character of the string by using for loop, and it will remove all the punctuation from the string.

You can refer to the below screenshot for how to remove punctuation from a string python

Remove the last character from string python

In python, for removing the last character from string python we will use the string slicing technique for removing the last character use negative index “my_string[:-1]” it will remove the last character of the string.

Example:

my_string = 'University'
remove_char = my_string[:-1]
print(remove_char)

After writing the above code (remove the last character from string python), Ones you will print “remove_char ” then the output will appear as a “ Universit ”. Here, we will use negative index -1 to remove the last character from the university.

You can refer to the below screenshot remove the last character from string python

Remove last 4 characters from string python

In python, for removing the last 4 character from string python we will use the string slicing technique for removing the last 4 character by using negative index “my_string[:-4]” and it will remove the last 4 character of the string.

Example:

my_string = 'University'
remove_char = my_string[:-4]
print(remove_char)

After writing the above code (remove last 4 characters from string python), Ones you will print “remove_char ” then the output will appear as a “ Univer”. Here, we will use a negative index -4 to remove the last 4 characters from the university.

You can refer to the below screenshot remove last 4 characters from string python

Python remove all whitespace from a string

In python, to remove all whitespace from a string we will use replace() to remove all the whitespace from the string.

Example:

my_string = " Welcome to Python "
remove = my_string.replace(" ", "")
print(remove)

After writing the above code (python remove all whitespace from a string), Ones you will print “remove” then the output will appear as a “ WelcometoPython ”. Here, we will use replace() to remove all the whitespace from the string.

You can refer to the below screenshot python remove all whitespace from a string

Python remove only leading and trailing spaces

In python, to remove only leading and trailing spaces we will use strip() function to remove the leading and trailing characters from start and end of the string.

Example:

my_string = " Welcome to Python \n\r\t "
remove = my_string.strip()
print(remove)

After writing the above code (python remove only leading and trailing spaces), Ones you will print “remove” then the output will appear as a “ Welcome to Python ”. Here, we will use strip() function to remove the leading and trailing characters and whitespaces from the start and end of the string.

You can refer to the below screenshot python remove only leading and trailing spaces.

Python remove only leading and trailing spaces

This is how python remove only leading and trailing spaces

Python split a string into equal half

In python, to split a string into equal half we will use string slicing method to split the string in equal half.

Example:

my_string = "PythonGuides"
string_first = my_string[:len(my_string)//2]
string_second = my_string[len(my_string)//2:]
print("My first part of string : " + string_first)
print("My second part of string : " + string_second)

After writing the above code (python split a string into equal half), Ones you will print then the output will appear as a “ My first part of string : Python, My second part of string : Guides ”. Here, we will use the string slicing method to split the string into equal half.

You can refer to the below screenshot python split a string into equal half

This is how python split a string into equal half

How to reverse a string in python

In python, to reverse a string in python there is no built-in function so, we will use slice that starts from the end of the string with a negative value and ends at 0.

Example:

my_string = "PythonGuide"[::-1]
print(my_string)

After writing the above code (how to reverse a string in python), Ones you will print then the output will appear as an “ ediuGnohtyP ”. Here, we will use the string slicing to reverse the string.

You can refer to the below screenshot python reverse a string in python

This is how to reverse a string in python

Check if a string is number python

In python, to check if all the characters are numeric we will use the method string.isnumeric() method which will return true if all the characters are number, otherwise false.

Example:

my_string = "101123"
a = my_string.isnumeric()
print(a)

After writing the above code (check if a string is number python), Ones you will print “a” then the output will appear as a “ True ”. Here, we will use isnumeric() method to check whether the string is number or not.

You can refer to the below screenshot python check if a string is number python
