Python Program to Check Whether Product of Digits at Even places of a Number is Divisible by K

In the previous article, we have discussed Python Program to Check Whether Sum of digits at Odd places of a Number is Divisible by K
The task is to check if the product of digits at even places of a given number is divisible by the another given input number say K.

Examples:

Example1:

Input:

Given  Number =  693214
Given  another Number (k) = 2

Output:

The Product of digits at even places of the given number{ 693214 } is divisible by the another given number k{ 2 }

Example2:

Input:

Given Number =  2578
Given another Number (k) = 4

Output:

The Product of digits at even places of the given number{ 2578 } is not divisible by the another given number k{ 4 }

Program to Check Whether Product of Digits at Even places of a Number is Divisible by K in Python

Below are the ways to check if the product of digits at even places of a given number is divisible by the another given input number say K:

Using For Loop (Static Input)
Using For loop (User Input)

Method #1: Using For Loop (Static Input)

Approach:

Give the number as static input and store it in a variable.
Give the other number k as static input and store it in another variable.
Convert the given number to a string using the str() function and store it in another variable.
Create a list of digits say “digtslst” using map(),list(),int functions.
Store it in another variable.
Take another variable say “evn_prodt” and initialize it with 1.
Loop in the above list of digits until the length of the “digtslst” using the for loop.
Check if the iterator value is even or not using the if conditional statement.
If the statement is true, then multiply the element of digits list at the iterator value to the “evn_prodt” and store it in the same variable evn_prodt.
Check if the evn_prodt modulus given number k is equal to 0 or not using the if conditional statement.
If the statement is true, then print “The product of digits at even places of the given number is divisible by the another given number k.
If the statement is false, then print “The product of digits at even places of the given number is Not divisible by the another given number k.
The Exit of the Program.

Below is the implementation:

# Give the number as static input and store it in a variable.
gvn_numb = 123456
# Give the other number k as static input and store it in another variable.
gvn_k = 5
# Convert the given number to a string using the str() function and store it in
# another variable.
stringnum = str(gvn_numb)
# Create a list of digits say "digtslst" using map(),list(),int functions.
digtslst = list(map(int, stringnum))
# Take another variable say "evn_prodt" and initialize it with 1.
evn_prodt = 1
# Loop in the above list of digits until the length of the "digtslst" using the for loop.
for itr in range(len(digtslst)):
    # Check if the iterator value is even or not using
    # the if conditional statement.
    if(itr % 2 == 0):
        # If the statement is true, then multiply the element of digits list at iterator value to
        # the "evn_prodt" and store it in the same variable evn_prodt.
        evn_prodt *= digtslst[itr]
# Check if the evn_prodt modulus given number k is equal to 0 or not using the if conditional
# statement.
if(evn_prodt % gvn_k == 0):
    # If the statement is true, then print "The product of digits at even places of the given
    # number is divisible by the another given number k.
    print("The Product of digits at even places of the given number{", gvn_numb,
          "} is divisible by the another given number k{", gvn_k, "}")
else:
    # If the statement is false, then print "The product of digits at even places of the given
    # number is Not divisible by the another given number k.
    print("The Product of digits at even places of the given number{", gvn_numb,
          "} is not divisible by the another given number k{", gvn_k, "}")

Output:

The Product of digits at even places of the given number{ 123456 } is divisible by the another given number k{ 5 }

Method #2: Using For loop (User Input)

Approach:

Give the number as user input using the int(input()) function and store it in a variable.
Give the other number k as user input using the int(input()) function and store it in another variable.
Convert the given number to a string using the str() function and store it in another variable.
Create a list of digits say “digtslst” using map(),list(),int functions.
Store it in another variable.
Take another variable say “evn_prodt” and initialize it with 1.
Loop in the above list of digits until the length of the “digtslst” using the for loop.
Check if the iterator value is even or not using the if conditional statement.
If the statement is true, then multiply the element of digits list at the iterator value to the “evn_prodt” and store it in the same variable evn_prodt.
Check if the evn_prodt modulus given number k is equal to 0 or not using the if conditional statement.
If the statement is true, then print “The product of digits at even places of the given number is divisible by the another given number k.
If the statement is false, then print “The product of digits at even places of the given number is Not divisible by the another given number k.
The Exit of the Program.

Below is the implementation:

#Give the number as user input using the int(input()) function and store it in a variable.
gvn_numb = int(input("Enter some random number = "))
#Give the other number k as user input using the int(input()) function and store it in another variable.
gvn_k = int(input("Enter some random number = ")) 
# Convert the given number to a string using the str() function and store it in
# another variable.
stringnum = str(gvn_numb)
# Create a list of digits say "digtslst" using map(),list(),int functions.
digtslst = list(map(int, stringnum))
# Take another variable say "evn_prodt" and initialize it with 1.
evn_prodt = 1
# Loop in the above list of digits until the length of the "digtslst" using the for loop.
for itr in range(len(digtslst)):
    # Check if the iterator value is even or not using
    # the if conditional statement.
    if(itr % 2 == 0):
        # If the statement is true, then multiply the element of digits list at iterator value to
        # the "evn_prodt" and store it in the same variable evn_prodt.
        evn_prodt *= digtslst[itr]
# Check if the evn_prodt modulus given number k is equal to 0 or not using the if conditional
# statement.
if(evn_prodt % gvn_k == 0):
    # If the statement is true, then print "The product of digits at even places of the given
    # number is divisible by the another given number k.
    print("The Product of digits at even places of the given number{", gvn_numb,
          "} is divisible by the another given number k{", gvn_k, "}")
else:
    # If the statement is false, then print "The product of digits at even places of the given
    # number is Not divisible by the another given number k.
    print("The Product of digits at even places of the given number{", gvn_numb,
          "} is not divisible by the another given number k{", gvn_k, "}")

Output:

Enter some random number = 693214
Enter some random number = 2
The Product of digits at even places of the given number{ 693214 } is divisible by the another given number k{ 2 }
