Python: is there a C-like for loop available?

Yes, this is how I would do it

>>> for i in xrange(0, 10):
...     if i == 4:
...         continue
...     print i,
...
0 1 2 3 5 6 7 8 9

EDIT
Based on the update to your original question... I would suggest you take a look at optparse

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)
  

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

In python would be written as

i = 0
while i < 10
   if someCondition
      i += 1
   print i
   i += 1

there you go, that is how to write a c for loop in python.

Strange way:

for x in (x for x in xrange(10) if someCondition):
    print str(x)
