search and replace with variable value

[nischalinn]

I've to search for a pattern and replace with input variable.
Suppose the strings are:

tempSearch : = '111-452-05'
tempSearch:= '111-452-10'
tempSearch:='11 1-459-15'
tempSearch: ='111-452-20'
tempSearch:='11 1-452-25'

search for the whole pattern starting from the "temp" to the end "'". I've to replace the value that is occuring after the first appearance of "-" with a user input value.

How can I do it?

Thank You!

Using str methods only:

>>> s = "tempSearch : = '111-452-05'"
>>> userStr = "XYZ"
>>> s[:s.index("-")+1]+userStr
"tempSearch : = '111-XYZ"
>>> 

Using re and str methods:

>>> import re
>>> s = "tempSearch : = '111-452-05'"
>>> userStr = "XYZ"
>>> patt = re.compile(r"-(.+)")
>>> m = patt.search(s)
>>> s.replace(m.group(1), userStr)
"tempSearch : = '111-XYZ"
>>>

Take a look at "Searching Text" and "Replacing Text" at http://www.freenetpages.co.uk/hp/alan.gauld/tuttext.htm You can also split on the "-" if that is easier to understand.

testing="tempSearch : = '111-452-05'"
replaced = "new part"
parts = testing.split("-")
print "parts =", parts
parts[1]=replaced
print "-".join(parts)
