'list' object is not callable

[azir99]

While reading the lines from the corpus of and saving it to this variables hindi and english.
And passing this variables to the preprocess method. The issue arises that is "list object is not callable" the error arises
in tokenize.py at line line 376, in read_or_stop
return readline()
Even if i pass direct path to the preprocess method that is helper.load(pathtocorpus)
It still gives the same error but this time it says "str object is not callable"
Can you help guide me to solve this error.
