Question

No matter what I try I keep getting an infinite loop with this function:

  # Excercise 33 - LPTHW

i = 0 
numbers = []

#Ec 1
#numb = 6
#iplus = 10

def theloop(numb):
        global i
        #i = 0
        #number = []
        while i < numb:
            print "At the top of i is %d" % i
            numbers.append(i)

            i = i + 1
            print "Numbers now: ", numbers
            print "At the bottom i is %d" % i

        print "The numbers: "

        for num in numbers:
            print num

theloop(7)

When I run the script it just keeps printing:

At the top of i is 0
At the top of i is 0
...

Thanks in advance.

Your code works for me as written, but looks to have weird indentation due to use of mixed tabs and spaces. When I read your script using .readlines, you can see this:

 '    def theloop(numb):\n',
 '    \t\tglobal i\n',
 '    \t\t#i = 0\n',
 '            #number = []\n',
 '    \t\twhile i < numb:\n',
 '     \t\t\tprint "At the top of i is %d" % i\n',
 '        \t\tnumbers.append(i)\n',
 '    \n',
 '        \t\ti = i + 1\n',

So I’d recommend switching to four spaces everywhere and having another go. Note the difference in the number of tabs between the print statement and the append/increment statements.
