Draw an M-shaped pattern with nested loops

Question

I just started Python 2.7 very recently, but I\'m stuck at this a problem:

Make a program that prints an \"M\" pattern of asterisks. The user shall in

Answer 1

Limitation: Enter only old number greater than 3

Logic:

1. Get input from user by raw_input().
2. Get number of space count by subtracting 2 from the user input. e.g. (i) for user input is 3 only first line have 1 space, (ii) for input 5--> first line have space 3 and second line have space 1.
3. Run for loop n time where n is user value.
4. If space count is greater then 0 then create print_line where add space value according to space count in the middle of string and * at start and end according to for loop count.
5. If space count is less then 0 then print string to * according to user value.

Code:

no = int (raw_input("Enter a number: "))
space_no = no - 2
print_line = "*"*no
for i in xrange(1,no+1):
    if space_no>0:
        print_line_n = "*"*i+" "*space_no+"*"*i
        space_no -=2
        print print_line_n
    else:
        print print_line

output:
