将字典写入 Python 中的文本文件 3

Question

This is my first post so please forgive me if there are errors/misunderstandings. I'm very new to python and trying to use it to improve and automate my everyday job as an IT technician.

My problem:

I have 15000+.txt files that have a four-digit number in each file (or not) that I'm using RegEx to retrieve, store in a dictionary, and print. This works well and fine for me! (code for this below)

import re, os
from os import listdir

txtfiles = [f for f in listdir("C:\\Users\\Redacted\\Redacted\\Redacted\\Redacted\\")]

txtlist = {}


for file in txtfiles:
    with open("C:\\Users\\Redacted\\Redacted\\Redacted\\Redacted\\" + file) as filename:
        for line in filename:
            if re.search('\(\w+\/3\d+@', line):
                entry = re.search('\/(\d+)', line).group(1)
                if entry in txtlist:
                    txtlist[entry] += 1
                else:
                    txtlist[entry] = 1

for key, value in txtlist.items():
    print(key, " : ", value)

This prints:

3008  :  36
3007  :  64
3015  :  68
3004  :  66
3017  :  32

Which is exactly what I want, yay me.

I'm now trying to get this to create a file in the same folder as all the other textfiles that will have the same formatting as the print call. Unfortunately, I'm getting the error:

Traceback (most recent call last):
  File "C:/Users/filepathofpycharmpytonfile", line 25, in <module>
    file.write(key, ' : ', value)
TypeError: write() takes exactly one argument (3 given)

Here is my code for the above error:

import re, os
from os import listdir

txtfiles = [f for f in listdir("C:\\Users\\Redacted\\Redacted\\Redacted\\Redacted\\")]

txtlist = {}


for file in txtfiles:
    with open("C:\\Users\\Redacted\\Redacted\\Redacted\\Redacted\\" + file) as filename:
        for line in filename:
            if re.search('\(\w+\/3\d+@', line):
                entry = re.search('\/(\d+)', line).group(1)
                if entry in txtlist:
                    txtlist[entry] += 1
                else:
                    txtlist[entry] = 1


with open("C:\\Users\\Redacted\\Redacted\\Redacted\\Redacted\\"1.Results.txt", "x" ) as file:
    for key, value in txtlist.items():
        file.write(key, ' : ', value)

So, my question is, how do I write the results to a file in the same way that I printed them to my console?

Thanks in advance!

PS To get around this, I wrote it as a JSON file which worked but obviously didn't keep the formatting I wanted. Please see code below:

import re, os
import json
from os import listdir

txtfiles = [f for f in listdir("C:\\Users\\Redacted\\Redacted\\Redacted\\Redacted\\")]

txtlist = {}


for file in txtfiles:
    with open("C:\\Users\\Redacted\\Redacted\\Redacted\\Redacted\\" + file) as filename:
        for line in filename:
            if re.search('\(\w+\/3\d+@', line):
                entry = re.search('\/(\d+)', line).group(1)
                if entry in txtlist:
                    txtlist[entry] += 1
                else:
                    txtlist[entry] = 1


with open("C:\\Users\\Redacted\\Redacted\\Redacted\\Redacted\\1.Results.txt", "x" ) as file:
    file.write(json.dumps(txtlist))

Answer 1

Try formatting what you want to write with an f-string:

file.write(f'{key} : {value}\n')

Answer 2

instead of file.write(key, ': ', value) try file.write(key + ': ' + value)

Concatting the strings instead of passing multiple arguments, because as the error states file.write only expexts one argument.

Answer 3

file.write only accepts a single string argument, but in your code file.write(key, ': ', value) , you are passing in three arguments. Change it, as the others mentioned, to a single string input.

Eg @mrblewog's answer

file.write(f'{key} : {value}')
