Last update on June 12 2025 12:43:12 (UTC/GMT +8 hours)

Insert space before capital letters.

Write a Python program to insert space before every capital letter appears in a given word.

Sample Data:
("PythonExercises") -> "Python Exercises"
("Python") -> "Python"
(“PythonExercisesPracticeSolution”) -> “Python Exercises Practice Solution”

Sample Solution:

Python Code:

# Define a function to insert a space before capital letters in a given word
def test(word):
    result = ""
    # Iterate through each character in the word
    for i in word:
        # Check if the character is uppercase
        if i.isupper():
            # Concatenate a space and the uppercase version of the character to the result
            result = result + " " + i.upper()
        else:
            # Concatenate the character to the result
            result = result + i
    # Remove the leading space from the result and return
    return result[1:]

# Initialize a string representing a word
word = "PythonExercises"

# Print the original word
print("Original Word:", word)

# Print a message indicating the insertion of space before capital letters
print("Insert space before capital letters in the said word:")

# Call the function to modify the word and print the result
print(test(word))

# Repeat the process with a different word
word = "Python"

# Print the original word
print("\nOriginal Word:", word)

# Print a message indicating the insertion of space before capital letters
print("Insert space before capital letters in the said word:")

# Call the function to modify the word and print the result
print(test(word))

# Repeat the process with a different word
word = "PythonExercisesPracticeSolution"

# Print the original word
print("\nOriginal Word:", word)

# Print a message indicating the insertion of space before capital letters
print("Insert space before capital letters in the said word:")

# Call the function to modify the word and print the result
print(test(word)) 

Sample Output:

Original Word: PythonExercises
Insert space before capital letters in the said word:
Python Exercises
Original Word: Python
Insert space before capital letters in the said word:
Python
Original Word: PythonExercisesPracticeSolution
Insert space before capital letters in the said word:
