Regex match string conditions

Since i'm not so good at regex how can i match some conditions in a string, StaticString_1number:1number:more than 1number.

Example:

string_3:0:12344555 - Match 
string_s:0:12344555 - No match 
string_3:s:12344555 - No match 
string_3:0:123s4555 - No match

Thanks.

This Regex would solve your problem:

^[a-zA-Z]+_[\d]{1}:[\d]{1}:[\d]+$

If I understand your pattern StaticString_1number:1number:more than 1number correctly your regex to match against such strings could look like the following:

'^[a-zA-Z]+_[0-9]:[0-9]:[0-9]+$'

or if your environment support character classes:

'^\w+_\d:\d:\d+$'

If the initial String can only have characters a-z then the following should work :

[a-z A-Z]+_\d:\d:\d+

this will match any number of letters up to an underscore then look for single digit before and after colon and multiple digits after second colon.

but you should really have an attempt your self. if in python you could try re-try or in javascript regexpal and try out your regex patterns there first.
