Python Exercises: Capitalize the first letter and lowercases the rest

Python String: Exercise-104 with Solution

Write a Python program that capitalizes the first letter and lowercases the remaining letters in a given string.

Sample Data:
(“Red Green WHITE) -> “Red Green White”
(“w3resource”) -> “W3resource”
(“dow jones industrial average”) -> “Dow Jones Industrial Average”

Sample Solution-1:

Python Code:

# Define a function to capitalize the first letter and lowercase the rest of each word in a string
def test(strs):
    # Use a generator expression to capitalize each word and join them with spaces
    return ' '.join(word.capitalize() for word in strs.split())    

# Initialize a string with words in various cases
text = "Red Green WHITE"
print("Original string:", text)

# Print a message indicating the capitalization of the first letter in each word
print("Capitalize the first letter and lowercases the rest:")

# Call the function to capitalize words and print the result
print(test(text))

# Repeat the process with a different string
text = "w3resource"
print("\nOriginal string:", text)

# Print a message indicating the capitalization of the first letter in each word
print("Capitalize the first letter and lowercases the rest:")

# Call the function to capitalize words and print the result
print(test(text))

# Repeat the process with another different string
text = "dow jones industrial average"
print("\nOriginal string:", text)

# Print a message indicating the capitalization of the first letter in each word
print("Capitalize the first letter and lowercases the rest:")

# Call the function to capitalize words and print the result
print(test(text)) 

Sample Output:

Original string: Red Green WHITE
Capitalize the first letter and lowercases the rest:
Red Green White

Original string: w3resource
Capitalize the first letter and lowercases the rest:
W3resource

Original string: dow jones industrial average
Capitalize the first letter and lowercases the rest:
Dow Jones Industrial Average

Sample Solution-2:

Python Code:

# Define a function to capitalize the first letter and lowercase the rest of each word in a string
def test(strs):
    # Use a generator expression to capitalize the first letter and lowercase the rest of each word
    return ' '.join(i[0].upper() + i[1:].lower() for i in strs.split())   

# Initialize a string with words in various cases
text = "Red Green WHITE"
print("Original string:", text)

# Print a message indicating the capitalization of the first letter in each word
print("Capitalize the first letter and lowercases the rest:")

# Call the function to capitalize words and print the result
print(test(text))

# Repeat the process with a different string
text = "w3resource"
print("\nOriginal string:", text)

# Print a message indicating the capitalization of the first letter in each word
print("Capitalize the first letter and lowercases the rest:")

# Call the function to capitalize words and print the result
print(test(text))

# Repeat the process with another different string
text = "dow jones industrial average"
print("\nOriginal string:", text)

# Print a message indicating the capitalization of the first letter in each word
print("Capitalize the first letter and lowercases the rest:")

# Call the function to capitalize words and print the result
print(test(text)) 

Sample Output:

Original string: Red Green WHITE
Capitalize the first letter and lowercases the rest:
Red Green White

Original string: w3resource
Capitalize the first letter and lowercases the rest:
W3resource

Original string: dow jones industrial average
Capitalize the first letter and lowercases the rest:
Dow Jones Industrial Average

Flowchart:
