Python String Methods

Python String Methods are built-in functions that allow us to manipulate strings. They are used to perform various operations on strings such as searching, replacing, splitting, and formatting.

1. capitalize()

This method capitalizes the first letter of a string.

Example:

str = "python programming"
print(str.capitalize())

Output: Python programming

2. count()

This method returns the number of times a specified value appears in a string.

Example:

str = "Python is a programming language"

print(str.count("a"))

Output: 1

3. endswith()

This method returns True if a string ends with the specified suffix, otherwise it returns False.

Example:

str = "Python is a programming language"
print(str.endswith("language"))

Output: True

4. find()

This method returns the index of the first occurrence of the specified value in a string.

Example:

str = "Python is a programming language"
print(str.find("a"))

Output: 11

5. format()

This method formats a specified string into a specified format.

Example:

str = "My name is {name}"
print(str.format(name="John"))

Output: My name is John

6. index()

This method returns the index of the first occurrence of the specified value in a string.

Example:

str = "Python is a programming language"
print(str.index("a"))

Output: 11

7. isalnum()

This method returns True if all characters in a string are alphanumeric, otherwise it returns False.

Example:

str = "Python123"
print(str.isalnum())

Output: True

8. isalpha()

This method returns True if all characters in a string are alphabetic, otherwise it returns False.

Example:

str = "Python"

print(str.isalpha())

Output: True

9. isdigit()

This method returns True if all characters in a string are digits, otherwise it returns False.

Example:

str = "12345"
print(str.isdigit())

Output: True

10. join()

This method joins all elements of an iterable to a string.

Example:

str = "-"
list = ["Python", "Programming", "Language"]
print(str.join(list))

Output: Python-Programming-Language
