Python: Create a two-dimensional list from given list of lists

Python List: Exercise - 264 with Solution

Write a Python program to create a two-dimensional list from given list of lists.

  • Use *nums to get the provided list as tuples.
  • Use zip() in combination with list() to create the transpose of the given two-dimensional list.

Sample Solution:

Python Code:

def two_dimensional_list(nums):
  return list(zip(*nums))
print(two_dimensional_list([[1, 2, 3], [4, 5, 6], [7, 8, 9], [10, 11, 12]]))
print(two_dimensional_list([[1, 2], [4, 5]]))

Sample Output:

[(1, 4, 7, 10), (2, 5, 8, 11), (3, 6, 9, 12)]
[(1, 4), (2, 5)]

Floor Division:

When we speak of division we normally mean (/) float division operator, this will give a precise result in float format with decimals.

For a rounded integer result there is (//) floor division operator in Python. Floor division will only give integer results that are round numbers.

print(1000 // 300)
print(1000 / 300)

Output:

3
