Python Code Demonstrating String Case Conversion

The following Python code demonstrates how to convert a string to uppercase, lowercase, and how to format it using capitalization methods like capitalize() and title().

Example: String Case Conversion

# Define the string
str = "www.pmeve.com"

# Convert all characters to uppercase
print(str.upper())          # Converts all lowercase letters to uppercase

# Convert all characters to lowercase
print(str.lower())          # Converts all uppercase letters to lowercase

# Capitalize the first letter of the string, and make the rest lowercase
print(str.capitalize())     # Capitalizes the first letter of the string

# Convert the first letter of each word to uppercase
print(str.title())          # Capitalizes the first letter of each word

Sample Output:

WWW.PMEVE.COM
www.pmeve.com
Www.pmeve.com
Www.Pmeve.Com
