如何将输出保存到txt文件？

When I got the number of how many times of the words, I wanted to save the output to a txt file. But when I used the following code, only counts appeared in the output file. Anyone knows the problem here? Thank you very much!

当我得到单词的次数时,我想将输出保存为txt文件。但是当我使用以下代码时,只有计数出现在输出文件中。谁知道这里的问题?非常感谢你!

My code: (part)

我的代码:(部分)

d = c.split() # make a string into a list of words
#print d
counts = Counter(d) # count the words 
print(counts)

import sys
sys.stdout = open("C:/Users/Administrator/Desktop/out.txt", "w")
print 'counts'

4 个解决方案

#1

import sys
from collections import Counter

c = "When I got the number of how many times of the words"
d = c.split() # make a string into a list of words
counts = Counter(d) # count the words 
sys.stdout = open("C:/Users/Administrator/Desktop/out.txt", "w")
print(str(len(d)) + ' words') #this shows the number of total words 
for i in counts:
    print(str(i), str(counts[i]) + ' counts')

With te result in out.txt

用te结果out.txt

12 words
When 1 counts
got 1 counts
many 1 counts
times 1 counts
the 2 counts
words 1 counts
I 1 counts
number 1 counts
how 1 counts
of 2 counts

Working as intended as python is a dynamic language and everything as it was during runtime. So in order to capture everything you will have to redirect your stdout at the begging of your script.

像python一样工作是一种动态语言,它在运行时是一样的。因此,为了捕获所有内容,您必须在脚本的乞讨时重定向stdout。

import sys
sys.stdout = open("C:/Users/Administrator/Desktop/out.txt", "w")
d = c.split() # make a string into a list of words
#print d
counts = Counter(d) # count the words 
print(counts)

print 'counts'

#3

import sys
d = c.split() # make a string into a list of words
#print d
counts = Counter(d) # count the words 
sys.stdout = open("C:/Users/Administrator/Desktop/out.txt", "w")
print(counts)
print 'counts'

print prints to stdout. You need to redirrect stdout to the file before printing the number of counts.

打印到stdout。在打印计数之前,您需要将stdout重新写入文件。

Another, slightly nicer option, would be to use some of the newer Python features:

另一个更好的选择是使用一些较新的Python功能:

from __future__ import print_function

with open(r'c:\Users\Administrator\Desktop\out.txt', 'w') as f:
    d = c.split() # make a string into a list of words
    #print(d, file=f)
    counts = Counter(d) # count the words 
    print(counts, file=f)

    print('counts', file=f)

Alternatively, you could use the logging module:

或者,您可以使用日志记录模块:

import logging

logger = logging.getLogger('mylogger')
logger.addHandler(logging.FileHandler(filename=r'c:\Users\Administrator\Desktop\out.txt'))
logger.setLevel(logging.DEBUG)


wordlist = c.split()
logger.debug('Wordlist: %s', wordlist)

logger.debug('Counting words..')
counts = Counter(wordlist)
logger.debug('Counts: %s', counts)

As it appears you're on Windows, you can use the incredibly useful baretail application to watch your log as your program executes.

由于您似乎在Windows上,因此您可以使用非常有用的裸尾应用程序在程序执行时查看日志。
