.write 在 Python 中不起作用 [英] .write not working in Python

问题描述

我对 Python 还很陌生，所以希望我只是在这里遗漏了一些明显的东西，但这让我很难过.下面是我的程序的片段:

I'm fairly new to Python so hopefully I'm just missing something obvious here, but it has me stumped. Snippet of my program below:

outFile = open('P4Output.txt', 'w')
outFile.write(output)
print output
print "Output saved to "P4Output.txt"
"

输出正确打印到控制台，但如果我打开文件，它是空白的.如果我删除该文件并再次执行我的程序，该文件已创建但仍然是空的.我之前在我的另一个程序中使用了这个完全相同的代码块，它有效，并且仍然有效.但是，如果我打开 Python 并尝试一些简单的操作，例如:

output prints correctly to the console, but if I go open up the file it's blank. If I delete the file and execute my program again, the file is created but still is empty. I used this exact same block of code in another program of mine previously and it worked, and still works. However, if I open up Python and try something simple like:

f = open('test.txt', 'w')
f.write("test")

同样，test.txt 已创建，但保留为空白.什么给?

Again, test.txt is created but is left blank. What gives?

推荐答案

你在程序结束时做了 f.close() 吗?

Did you do f.close() at the end of your program?
