Python Modify Strings

Modify Strings in Python

Python has several built-in methods for modifying strings:

• Uppercase: Convert the string to uppercase:

1
2
a = "Hello, World!"
print(a.upper())  # Output: 'HELLO, WORLD!'

• Lowercase: Convert the string to lowercase:

1
print(a.lower())  # Output: 'hello, world!'

• Remove Whitespace: Use strip() to remove spaces from the beginning and end:

1
2
a = " Hello, World! "
print(a.strip())  # Output: 'Hello, World!'

• Replace String: Replace characters or substrings using replace():

1
print(a.replace("H", "J"))  # Output: 'Jello, World!'

• Split String: Use split() to split a string into a list based on a separator:

1
print(a.split(","))  # Output: ['Hello', ' World!']
