将字典正确输出到文件（fimi格式）python

Question

I have a text file containing string values separated by space " ". I need to set each of those string values to be equal to a some number. So far I have done a reading from the file to a dictionary where each unique key corresponds to a value number.

import collections 

with open('test.txt', 'r') as f:
     c = collections.Counter(f.read().split())

newvalue = 0
for key, value in c.iteritems():
    newvalue +=1
        c[key] =  newvalue
    print key, newvalue

My problem is now that I don't know how to write the output in another file, keeping this structure:

my text file:

• computer phone library desk book
• book yard spring phone
• book spring

desired output file:

• 1 2 3 4 5
• 5 6 7 2
• 5 7

Can someone please help me?

A few problems:

1. Counter objects do not have an iteritems method.
2. Indentation.
3. Splitting the whole file at once produces a single list, destroying the desired layout.

Here is a working sample that does what you want. The biggest change is to preserve the layout of the input file by using nested lists.

import collections 

with open('test.txt', 'r') as f: # open the file
    lines = [] # initialize a list
    for line in f: # for each line in the file,
        # add a list of that line's words to the initialized list
        lines.append(line.split())
    # save a Counter out of the concatenation of those nested lists
    c = collections.Counter(sum(lines, []))

with open('testout.txt', 'w') as output: # start a file
    for line in lines: # for each list in the list we made,
        result = [] # initialize a list
        for word in line: # for each word in the nested list,
            # add that word's count to the initialized list
            result.append(str(c[word]))
        # write a string representation of the list to the file
        output.write(' '.join(result) + '\n')
