Python String is the sequence of characters enclosed in either single (' '), double (" "), or triple (''' ''' or """ """) quotes.

Creating Strings

Strings can be created using single, double, or triple quotes.

single_quoted_str = 'Hello, World!'
double_quoted_str = "Python Programming"
triple_quoted_str = '''This is a multi-line
string in Python'''

Important: You can use triple quotes to create a string with multiple lines, character \n is in triple_quoted_str.

Example:

multi_line_string = '''
This is a string
with multiple lines
using triple quotes.
'''
print("---start---")
print(multi_line_string)
print("---end---")

Output:

---start---

This is a string
with multiple lines
using triple quotes.

---end---

Concating String

Strings can be concatenated using the + operator.

str1 = "Hello,"
str2 = " World!"
concatenated_str = str1 + str2

Indexing String

Individual characters in a string can be accessed using index numbers (starting at 0).

my_str = "Python"
char = my_str[0]  # Accessing the first character 'P'

Slicing String

You can use the syntax [start:stop:step] to extract substrings.

my_str = "Python Programming"
substring = my_str[7:18]  # Extracts "Programming"

Reversing String

You can use string slicing to reverse a string.

my_string = "Hello, World!"
reversed_string = my_string[::-1]
print(reversed_string)  # Output: "!dlroW ,olleH"
