Question

Can I do something like this in Python?

for (i = 0; i < 10; i++):
  if someCondition:
     i+=1
  print i

I need to be able to skip some values based on a condition

EDIT: All the solutions so far suggest pruning the initial range in one way or another, based on an already known condition. This is not useful for me, so let me explain what I want to do.

I want to manually (i.e. no getopt) parse some cmd line args, where each ‘keyword’ has a certain number of parameters, something like this:

for i in range(0,len(argv)):
    arg = argv[i]
    if arg == '--flag1':
       opt1 = argv[i+1]
       i+=1
       continue
    if arg == '--anotherFlag':
       optX = argv[i+1]
       optY = argv[i+2]
       optZ = argv[i+3]
       i+=3
       continue

    ...

There are two things you could do to solve your problem:

• require comma-separated arguments which are going to be grouped into the following option value, you could use getopt, or any other module then.

• or do more fragile own processing:

  sys.argv.pop()
  cmd = {}
  while sys.argv:
      arg = sys.argv.pop(0)
      if arg == '--arg1':
          cmd[arg] = sys.argv.pop(0), sys.argv.pop(0)
      elif:
          pass
  print(cmd)
