Looped Nesting -- Factorising

I am trying to write a program that takes a user input, limit and prints a table to visualise all the factors of each integer ranging from 1 to the limit. Each row represents an in

Solution 1:

You should use the variable i or limit in your inner loop as well. So you will generate a limit * limit output. Also you have to iterate until limit + 1 to get full limit rows.

A detailed version:

# get a maximim number and cast it to int
limit = int(input('Maximum number to factorise: '))

# prints a header [1; limit]
print " " + "".join(["%3d" % i for i in xrange(1, limit + 1)])
# outer loop: [1; limit]
for i in range(1, limit + 1):
    line = '%2d ' % i  # format string row number
    # inner loop: [1; limit]!
    for j in range (1, i + 1):  # you can also set limit + 1
        if i % j:  # if i % != 0
            line += '-  '
        else:
            line += '*  '
    print(line)

Generates:

   1  2  3  4  5  6  7  8  9 10 11 12 13 14 15 16 17 18 19 20

Solution 2:

You want something like:

limit = input('Maximum number to factorise: ')
for i in range(1,int(limit)):
    line = '{:2}:'.format(i)
    for j in range (1,11):
        if i % j == 0:
            line += "{:4}".format('0')
        else:
            line += "{:4}".format('-')
    print(line)
