Python String Operations

String Creation:

my_string = "Hello, World!"
    

String Concatenation:

str1 = "Hello"
str2 = "World"
result = str1 + " " + str2
    

String Multiplication:

str1 = "Hello "
result = str1 * 3 # "Hello Hello Hello "
    

String Length:

my_string = "Hello, World!"
length = len(my_string) # 13
    

Accessing a Specific Character:

my_string = "Hello, World!"
char = my_string[0]  # "H"
    

String Slicing:

my_string = "Hello, World!"
slice = my_string[2:7]  # "llo, "
    

Converting All Characters to Upper or Lower Case:

my_string = "Hello, World!"
upper_case = my_string.upper()
lower_case = my_string.lower()
    

Splitting a String by a Specific Character:

my_string = "Hello, World!"
parts = my_string.split(",")
    

Stripping Spaces:

my_string = " Hello, World! "
cleaned_string = my_string.strip()
    

String Formatting:

name = "John"
age = 30
formatted_string = "My name is {} and I am {} years old.".format(name, age)
    

Replacing Characters in a String:

my_string = "Hello, World!"
new_string = my_string.replace("o", "e")  # "Helle, Werld!"
    

Finding the Index of a Specific Character:

my_string = "Hello, World!"
index = my_string.index("o")  # 4
