Strings

What are Strings?

A string is simply a sequence of characters enclosed within quotes. These are all strings:


"Hello, World!"
'A'
"12345"
'These are Special characters: !@#$%^&*()'

You can use either single quotes (') or double quotes (") to create a string in Python. Just make sure to use the same type of quote at the beginning and end of the string.

Creating String Variables

You can create a string variable just like any other variable. Here’s an example:


# Example of a string variable
greeting = "Hello, World!"

Anything enclosed in quotes is considered a string, even if it looks like a number. For example, "12345" is a string, not a number.

Operations with Strings

Just like with numeric types, you can perform various operations with strings. Here are some examples:


# Concatenation
greeting = "Hello, "
name = "Alice"
full_greeting = greeting + name  # full_greeting will be "Hello, Alice"
 
# Repetition
laugh = "Ha"
laughter = laugh * 3  # laughter will be "HaHaHa"
 
# Accessing Characters
word = "Python"
first_letter = word[0]  # first_letter will be 'P'
last_letter = word[-1]  # last_letter will be 'n'

You will most often be using concatenation. The other operations are less common but still useful in certain situations.
