Depending on exactly what the general format of the string is, this might
be what you want:
>>> int(''.join([c for c in 'X= 45 A' if c in '0123456789']))
Or, possibly less obscure (untested though):
startStr = 'X= 45 A'
intsInStr = 
for c in startStr:
if c in '0123456789':
intStr = ''.join(intsInStr)
finalInt = int(intStr)
Should hopefully result in 45 :)
Untested, and... ehrm... with room for optimisation ;)
