Algorithm to Print Pascal’s Triangle in Python

  1. Step – 1: Taking input from the user to get the number of rows.
  2. Step – 2: Declare an empty list that will store the values.
  3. Step – 3: Using for loop, which will iterate through 0 to n – 1, append the sub-lists to the list.
  4. Step – 4: Now append 1 to the list.
