Python: Decapitalize the first letter of a given string

Last update on December 21 2024 07:47:10 (UTC/GMT +8 hours)

Decapitalize first letter in string.

Write a Python program to decapitalize the first letter of a given string.

• Use list slicing and str.lower() to decapitalize the first letter of the string.
• Use str.join() to combine the lowercase first letter with the rest of the characters.
• Omit the upper_rest parameter to keep the rest of the string intact, or set it to True to convert to uppercase.

Sample Solution:

Python Code:

# Define a function to decapitalize the first letter of a string
# Optionally, capitalize the rest of the string if 'upper_rest' is True (default is False)
def decapitalize_first_letter(s, upper_rest=False):
    # Join the first letter in lowercase with the rest of the string, optionally capitalizing the rest
    return ''.join([s[:1].lower(), (s[1:].upper() if upper_rest else s[1:])])
	
# Test the function with different input strings and print the results
print(decapitalize_first_letter('Java Script'))
print(decapitalize_first_letter('Python')) 

Sample Output:

java Script
