Python storing a sting + variable + string into a variable -


i have dilemma middle of file name change beginning , end remain same. trying store final result in variable confused on how this.

ips=['10.240.10.5','10.232.10.5','10.200.10.5','10.200.10.6','10.232.10.6','10.240.10.6','10.200.10.7','10.200.10.7']  in ips:         sessionfile = 'sdee_sid_' . i[0] . '.data'         f = open(sessionfile, r)         subscription = f.read()

i getting errors sessionfile variable...

file "closeallsdeesession.py", line 8     sessionfile = "sdee_sid_" . i[0] . ".data"                                              ^

there's no string concatenation operator in python, use +:

'sdee_sid_' + + '.data'

or printf-like string formatting:

'sdee_sid_%s.data' %

or new-style string formatting:

'sdee_sid_{}.data'.format(i)

note i[0] first character of i, might not want.
