Reading a file into a list on python. How to take out words -

i reading file list , spliting every word in list. not want specific words brought in list, skip them. called trash list filterlist written below.

this code:

with open('usconstitution.txt') f:     lines = f.read().split()              #read list  filterlist = ["a","an","the","as","if","and","not"]  #define filterlist  word in lines:     if word.lower() not in filterlist:         word.append(alist)   #place them in new list called alist not contain in filterlist   print(alist)    #print new list 

i getting error:

attributeerror: 'str' object has no attribute 'append' 

can ? thanks

you need give,

alist.append(word) 

list object has attribute append. , need declare list first. append items list.

ie,

with open('usconstitution.txt') f:     lines = f.read().split()              #read list  filterlist = ["a","an","the","as","if","and","not"]  #define filterlist alist = [] word in lines:     if word.lower() not in filterlist:         alist.append(word)   #place them in new list called alist not contain in filterlist   print(alist)
