In this article, We will see How to Convert the Centimeter unit into Inches.
Example:

Input: Centimeter: 8
Output: Inches: 3.152 

As we know that, 1 centimeter = 0.394 inches (approx) so we are using this information for writing this program.

Now, let’s see the different ways to code this program:
Code 1:

# given input
centimeter = 8

# conversion factor mention
conversion_factor = 0.394

# conversion from centimeter to inches
inches = centimeter * conversion_factor

# print
print("Centimeter Units:", centimeter)
print("One Centimeter is equal to", conversion_factor, "inches")
print("So",centimeter,"Centimeter is equal to:", inches,"inches")

Output:

Centimeter Units: 8
One Centimeter is equal to 0.394 inches
So 8 Centimeter is equal to: 3.152 inches

Code 2: By creating user-defined function.

# Create a user defined function for
# conversion from centimeter to inches
def centi_to_inches(centimeter) :
    
    # conversion factor mention
    conversion_factor = 0.394

    # conversion from centimeter to inches
    inches = centimeter * conversion_factor

    # print
    print("Centimeter Units:", centimeter)
    print("One Centimeter is equal to", conversion_factor, "inches")
    print("So",centimeter,"Centimeter is equal to:", inches,"inches")

# Main code
if __name__ == "__main__" :

    # given input
    centimeter = 8

    # function calling
    centi_to_inches(centimeter)

Output:

Centimeter Units: 8
One Centimeter is equal to 0.394 inches
So 8 Centimeter is equal to: 3.152 inches

Code 3: By Creating anonymous : one- line function

# Create a anonymous/lambda function for
# conversion from centimeter to inches
convert = lambda centi : centi * 0.394

# Main code
if __name__ == "__main__" :

    # given input
    centimeter = 8

    # print
    print("Centimeter Units:", centimeter)

    # function calling and printing
    print(centimeter,"Centimeter is equal to:", convert(centimeter),"inches")

Output:

Centimeter Units: 8
8 Centimeter is equal to: 3.152 inches

Code 4: In this code, we are taking input from user and convert it into integer and then pass it into convert anonymous function.

# Create a anonymous/lambda function for
# conversion from centimeter to inches
convert = lambda centi : centi * 0.394

# Main code
if __name__ == "__main__" :

    # take input from user and
    # convert it into integer data type
    centimeter = int(input("Enter centimeter units:"))

    # print
    print("Centimeter Units:", centimeter)

    # function calling and printing
    print(centimeter,"Centimeter is equal to:", convert(centimeter),"inches")

Output:

Enter centimeter units:10
Centimeter Units: 10
10 Centimeter is equal to: 3.9400000000000004 inches
