Convert Integers List to Single Integer

Write a Python program to convert a list of multiple integers into a single integer.

Sample Solution:

Python Code:

# Define a list 'L' containing numeric elements
L = [11, 33, 50]

# Print the original list 'L'
print("Original List: ", L)

# Use the 'join' function to convert the elements of 'L' to a single string, then convert it to an integer 'x'
x = int("".join(map(str, L)))

# Print the single integer 'x'
print("Single Integer: ", x)

Sample Output:

Original List:  [11, 33, 50]                                                                                  
Single Integer:  113350
