As indicated by the other answers, the error is to due to k = list[0:j]
, where your key is converted to a list. One thing you could try is reworking your code to take advantage of the split
function:
# Using with ensures that the file is properly closed when you're done with open('filename.txt', 'rb') as f: d = {} # Here we use readlines() to split the file into a list where each element is a line for line in f.readlines(): # Now we split the file on `x`, since the part before the x will be # the key and the part after the value line = line.split('x') # Take the line parts and strip out the spaces, assigning them to the variables # Once you get a bit more comfortable, this works as well: # key, value = [x.strip() for x in line] key = line[0].strip() value = line[1].strip() # Now we check if the dictionary contains the key; if so, append the new value, # and if not, make a new list that contains the current value # (For future reference, this is a great place for a defaultdict :) if key in d: d[key].append(value) else: d[key] = [value] print d # {'AAA': ['111', '112'], 'AAC': ['123'], 'AAB': ['111']}
Note that if you are using Python 3.x, you’ll have to make a minor adjustment to get it work properly. If you open the file with rb
, you’ll need to use line = line.split(b'x')
(which makes sure you are splitting the byte with the proper type of string). You can also open the file using with open('filename.txt', 'rU') as f:
(or even with open('filename.txt', 'r') as f:
) and it should work fine.
