Question

我每两周启动一个脚本，以刮擦3位记录数字的行的文件。我经常这样做，我想为什么不做一个可以导入的函数。我写了这个然后去测试。但是，当我运行脚本并执行

def_recs(filename, out)

我明白了 “ NameError：名称'文件名'未定义” 其中“文件名”是我要抓取的有问题文件的名称。

这是我的代码：

import os
import re

def get_recs(infile, outfile):
    path = r'<path to my infile file>'
    with open(os.path.join(path, infile),'r') as infile1:
        with open(os.path.join(path, outfile),'w') as outfile1:
            for line in infile1:
                if re.match(r'(.*)\d\d\d(.*)',line):
                    outfile1.writelines(line)

将其保存在名为“ ToolBelt.py”的文件中。我的最终目标是能够执行以下操作：

from ToolBelt import get_recs
get_rec(newfile, out)

，并将所有连续三位数的记录写入名为“ out”或我作为第二个参数传递的文件的文件。

编辑：仅需添加，当我将上述代码修改为不起作用时：

import os
import re

path = r'<path to my infile file>'
with open(os.path.join(path, 'newfile'),'r') as infile1:
    with open(os.path.join(path, 'out'),'w') as outfile1:
        for line in infile1:
            if re.match(r'(.*)\d\d\d(.*)',line):
                outfile1.writelines(line)

运行正常。

Edit2：刚刚尝试将其更改为

import os
import re

def get_recs(infile, outfile):
    if type(infile) != str:
        infile = str(infile)
    if type(outfile) != str:
        outfile = str(outfile)
    path = r'<path to my infile file>'
    with open(os.path.join(path, infile),'r') as infile1:
        with open(os.path.join(path, outfile),'w') as outfile1:
            for line in infile1:
                if re.match(r'(.*)\d\d\d(.*)',line):
                    outfile1.writelines(line)

仍然收到NameError。我现在正在网上搜索传递字符串参数的正确方法。
