#38968 — Howto parse a string using a char in python

Hi,

I am looking for the python2.7 function(s) to parse a string from a colon 
character ":"

Sounds simple enough.

For example, a string like "123456:789".  I just need the "123456" 
substring.(left of the :)

I have looked at regular expressions and string functions, so far no luck. 
Custom function required?

Thank you.

Use the split() string function.

With just a single character, it sounds like you want something like

  whole = "123456:789"
  parts = whole.split(':') # or .split(':', 1)
  interesting = parts[0]

No custom function needed.

"123456:789".split(":")[0]

More likely a visit to the opticians :)  See 
http://docs.python.org/2/library/stdtypes.html#string-methods for the 
find and index methods.

How about:

newstr = str[:str.find(':')]
