Strings

Strings are used to represent text data in Python. In Python, a string is represented by str class. We can create a string by enclosing text data in single quotes (') or double quotes (").

Here's an example:

# Example of string
x = 'Hello, World!'
y = "This is a string."
print(x)
print(y)

Output:

Hello, World!
This is a string.

String Operations

We can perform various operations on strings in Python. Here are some common string operations:

• Concatenation: We can concatenate two or more strings using the + operator.
• Repetition: We can repeat a string a certain number of times using the * operator.
• Indexing: We can access a specific character in a string using its index.
• Slicing: We can extract a part of a string using slicing.
• Length: We can find the length of a string using the len() function.
• Upper/Lower Case: We can convert a string to upper or lower case using the upper() and lower() methods.

Here are some examples:

# Example of string operations
x = 'Hello,'
y = ' World!'
z = x + y
print(z)

a = 'Hello,'
b = a * 3
print(b)

c = 'Python'
print(c[0])  # access first character
print(c[1:4])  # slice from index 1 to 4
print(len(c))  # length of string

d = 'Python is awesome'
print(d.upper())  # convert to upper case
print(d.lower())  # convert to lower case

Output:

Hello, World!
Hello,Hello,Hello,
P

String Formatting

String formatting is used to create formatted strings. In Python, we can use the format() method to format strings. We can specify placeholders in a string using curly braces {} and pass values to those placeholders using the format() method.

Here's an example:

# Example of string formatting
x = 'John'
y = 'Doe'
z = 'My name is {} {}.'.format(x, y)
print(z)

Output:

My name is John Doe.

We can also use f-strings to format strings in Python 3.6 and above:

# Example of f-string
x = 'John'
y = 'Doe'
z = f'My name is {x} {y}.'
print(z)

Output:

My name is John Doe.
