I have a python script which process a file line by line, if the line
matches a regex, it calls a function to handle it.
My question is is there a better write to refactor my script. The
script works, but as it is, i need to keep indent to the right of the
editor as I add more and more regex for my file.
Thank you for any idea.
Now my code end up like this:
for line in fi.readlines():
This will read all the lines and then iterate through them. You can
iterate through the file line by line directly with:
for line in fi:
...
result= reg1.match(line)
if result:
handleReg1(result)
else:
result = reg2.match(line)
if result:
handleReg2(result)
else:
result = reg3.match(line)
if result:
handleReg3(result)
else:
result = reg4.match(line)
if result:
handleReg4(result)
else:
result = reg5.match(line)
if result:
handleReg5(result)
Build a list of the regexes and their functions:
actions = []
actions.append((reg1, handleReg1))
actions.append((reg2, handleReg2))
actions.append((reg3, handleReg3))
actions.append((reg4, handleReg4))
actions.append((reg5, handleReg5))
for line in fi:
for reg, func in actions:
result = reg.match(line)
if result:
func(result)
break
