Below is the code to draw the pattern
Code:
def pattern_4(num):
# initialising starting number
number = 1
# outer loop always handles the number of rows
# let us use the inner loop to control the number
for i in range(0, num):
# commenting the reinitialization part ensure that numbers are printed continuously
# ensure the column starts from 0
number = 0
# inner loop to handle number of columns
for j in range(0, i+1):
# printing number
print(number, end=" ")
# increment number column wise
number = number + 1
# ending line after each row
print("\r")
num = int(input("Enter the number of rows in pattern: "))
pattern_4(num)
