    else:
        start_nocode()#a pre defined fun not shown here```

Answer 1

You can take advantage of return here. It will stop your method right there and nothing below that in that method will be executed

def start():
    code = '1037'
    source = input('Your Name')
    if source==code:
        dev() # Not defined in this code
        return
    else:
        start_nocode()#a pre defined fun not shown here
    print('Program Finished')
