Convert a tuple into a list by adding the string after every element of the tuple

In this python tuple program, we will convert a tuple into a list by adding the string after every element of the tuple.

Steps to solve the program

Take a tuple and a string as input.
Create an empty list.
Use a for loop to iterate over elements in the tuple.
Add the element and the string to the empty list using append().
Repeat the process for all elements.
Print the output.

				
					a = (1,2,3,4)
print("Tuple: ",a)
b= 'sqatools'
print("String: ",b)
l = []
for ele in a:
    l.append(ele)
    l.append(b)

Output :

				
					Tuple:  (1, 2, 3, 4)
String:  sqatools
New list:  [1, 'sqatools', 2, 'sqatools', 3, 'sqatools', 4, 'sqatools']

Take a list of tuples as input.
Create a variable i and product set their value equal to 1.

Use a for loop to iterate over tuples from the list.
Create a count variable and assign its value equal to 0.
Use a nested for loop to iterate over elements in the tuple.
If an element is divisible by 5 then add 1 to the count variable.
In the end, if the value of the count variable is equal to the length of the tuple i.e. total elements in the tuples, then that entire tuple is divisible by 5.
Print the output.

				
					l = [(10,5,15),(25,6,35),(20,10)]
