Hit count: 237
string='a'
p=0
while (p <len(string)) & (string[p]!='c') :
p +=1
print ('the end but the process already died ')
while (p <1) & (string[p]!='c') :
IndexError: string index out of range
I want to test a condition up to the end of a string (example string length=1)
why are both parts of the and executed is the condition is already false!
as long as p < len(string). the second part does not even need executing.
if it does a lot of performance can be lost
