Python: Triple all numbers of a given list of integers using map function

Python map: Exercise-1 with Solution

Write a Python program to triple all numbers in a given list of integers. Use Python map.

Sample Solution:

Python Code :

# Create a tuple named 'nums' containing the numbers 1 through 7
nums = (1, 2, 3, 4, 5, 6, 7)

# Print the original list of numbers
print("Original list: ", nums)

# Use the map function to apply a lambda function that triples each element in 'nums'
result = map(lambda x: x + x + x, nums)

# Print the result of the map operation as a list
print("\nTriple of said list numbers:")
print(list(result))

Sample Output:

Original list:  (1, 2, 3, 4, 5, 6, 7)

Triple of said list numbers:
[3, 6, 9, 12, 15, 18, 21]
