arrays - python variable contains three lists not one -

i'm writing program in python read file , turn file a list of words. @ moment gives me 4 lists (one each line of file) function rstrip() doesn't seem working , i'm not sure why.

fname = raw_input("enter file name: ") fread = open(fname)  line in fread:     line = line.rstrip()     lst = line.split()     print lst 

i going speculate want join lists each line. can list.extend.

lst = [] line in fread:     line = line.rstrip()     lst.extend(line.split())  print lst 

another way of doing might

lst = fread.read().strip().split() 

also, in either case, don't forget close file.

fread.close()
