String operations

Write a program that demonstrates various string operations in Python.

# String Concatenation
string1 = "Hello, "
string2 = "world!"
concatenated_string = string1 + string2
print("Concatenation:", concatenated_string)

# String Repetition
repeated_string = string1 * 3
print("Repetition:", repeated_string)

# String Indexing and Slicing
print("Indexing:", concatenated_string[7])
print("Slicing:", concatenated_string[7:12])

# String Length
string_length = len(concatenated_string)
print("Length:", string_length)

# String Membership
print("Membership:", "world" in concatenated_string)

# String Comparison
print("Comparison:", string1 < string2)

# String Formatting
name = "Alice"
age = 25
print("Formatting:", f"{name} is {age} years old.")

# String Methods
uppercase_string = concatenated_string.upper()
lowercase_string = concatenated_string.lower()
stripped_string = "   trimmed string   ".strip()
replaced_string = concatenated_string.replace("world", "Python")
print("Upper:", uppercase_string)
print("Lower:", lowercase_string)
print("Strip:", stripped_string)
print("Replace:", replaced_string)

# String Iteration
for char in concatenated_string:
    print("Iteration:", char)

note

To compile and run the program, you can use the following commands:

python3 foo.py
