How to make an activation flag?

[Krszt]

Hello,
I have a program, which runs well.
It looks like

os.chdir('zips')
a = open("ziplist.txt", "w")
for path, subdirs, files in os.walk(r'./'):
    for filename in files:
        if filename.endswith(".zip"):
            commands....
            for line in open('%s.txt' % (date_ID)).readlines():
                if line.startswith('range_samples:'):
                    commands...
                    os.chdir('../')

Now I want to expand it with an if/else statement as an activation flag, something like: if the first argv is 1, run the whole program written above
and else do nothing.

I am trying it like this:

if activate_flag == 1 :
    os.chdir('zips')
    a = open("ziplist.txt", "w")
    for path, subdirs, files in os.walk(r'./'):
        for filename in files:
            if filename.endswith(".zip"):
                commands....
                for line in open('%s.txt' % (date_ID)).readlines():
                    if line.startswith('range_samples:'):
                       commands...
                       os.chdir('../')
else: 
   print("NO")

But it just write out the else statement: NO
Where is my mistake?

If you want it to do nothing when the flag is 0, just remove the else clause. Or is there something you want it to do when the flag is 0?

Show us how you assign the value of activation_flag before that if statement. Wild guess - it's a str and that is why '1' != 1

Yes, Itried, but my problem is that it doesnt do anything.
