Python | Pattern Generation using time() module
  • Last Updated : 08 Jun, 2020

This article aims to print patterns using the time() module in python.
Examples:

Input :
5
Output :
5 patterns using time with 5 rows

Input :
4
Output :
5 patterns using time with 4 rows, but for diamond if you
will enter even number of rows, it will automatically do (row+1)

# Print triangles by giving the number of stars:
  
# For Diamond, an odd number of stars will give a better result,
# If the number is even then for diamond pattern,
# it will automatically do (row + 1):
