Nested loops

Ex: wap to display *’s in pyramid style or triangle shape

n=int(input("enter no of rows "))

for i in range(1,n+1):

    print(" "*(n-i),end="")

    print("* "*i)

"""output:

enter no of rows 3

  *

 * *

* * *

Nested Loops:

Loop inside a loop is called Nested Loops.

Nested Loops:

for i in range(2):

    for j in range(2):

        print(i,j)

"""output:

0 0

0 1

1 0

1 1

>>> """

for i in range(1,2):

    for j in range(2):

        print(i,j)

output:

1 0

1 1

>>> 

#find out the output:
n=int(input("enter no of rows:")) for i in range(1,n+1):     for j in range(1,n+1):         print("*",end=" ")     print()	#find out the output: n=int(input("enter no of rows:")) for i in range(1,n+1):     print("* " *i)
enter no of rows:3 * * * * * *	enter no of rows:3 * * * * * *
