需要整数吗?打开() [英] An integer is required? open()

问题描述

我有一个非常简单的 Python 脚本，它应该扫描一个文本文件，该文件包含格式为 id='value' 的行并放入他们进入一个字典.python 模块名为 chval.py，输入文件为 in.txt.这是代码:

I have a very simple python script that should scan a text file, which contains lines formatted as id='value' and put them into a dict. the python module is called chval.py and the input file is in.txt. here's the code:

import os,sys
from os import *
from sys import *

vals = {}

f = open(sys.argv[1], 'r')

for line in val_f:
    t = line.split('=')
    t[1].strip('\'')
    vals.append(t[0], t[1])

print vals

f.close()

当我尝试运行它时，我得到:

when i try to run it i get:

回溯(最近一次调用最后一次):
文件chval.py"，第 9 行，在 ?f = open(sys.argv[1], 'r') 类型错误:需要一个整数

Traceback (most recent call last):
File "chval.py", line 9, in ? f = open(sys.argv[1], 'r') TypeError: an integer is required

我正在使用 python 2.4...因为我被要求不使用任何更新的东西，有没有我不知道的关于 open() 的东西?为什么它需要一个整数?

I'm using python 2.4... because i've been challenged to not use anything newer, is there something about open() that I don't know about? Why does it want an integer?

该行之后的任何内容都未经测试.简而言之:为什么会出现错误，我该如何解决?

anything after that line is untested. in short: why is it giving me the error and how do i fix it?

推荐答案

因为你做了 from os import *，你(偶然)使用了 os.open，它确实需要一个整数标志而不是文本r"或w".去掉那条线，你就会克服那个错误.

Because you did from os import *, you are (accidenally) using os.open, which indeed requires an integer flag instead of a textual "r" or "w". Take out that line and you'll get past that error.
