How to draw shapes in python?

From what i understood you are asking the user to input the shape and amount of rows. When this program prompts the user to input rows he should type 10 for any shapes given, however if you don't want the user to choose the amount of rows just comment out the #j=int(input("Enter rows: ")) and replace it with a global variable j=10.

s=str(input("Enter your shape(s for square, t for triangle or r for rectangle): "))
j=int(input("Enter rows: "))
shape=str(s)


if shape == 't':
    print("   I'm a pyramid")
    print()

    for x in range(0,j):
        for z in range(0,j-x-1):
            print(end=" ")
        for z in range(0,2*x+1):
            print('#',end="")
        print()

    print()
    print("   I'm a pyramid")
    print('____________________')
    print()


elif shape == 's':
    print("   I'm a square")
    print()

    for x in range (1,10):
        for z in range(20,1,-1):
            print("#", end='')
        print(' ')

    print()
    print("   I'm a square")
    print('____________________')
    print()

elif shape =='r':
    print("   I'm a rectangle")
    print()

    for x in range (1,10):
        for z in range(40,1,-1):
            print("#", end='')
        print(' ')

    print()
    print("   I'm a rectangle")
    print('____________________')
    print()

else:
    print('Only the options given mate')
