Question

我有一堆.status文件，我想要更改哪些内容。我写了一个简单的脚本：

FREQNAMES = ['YEARLY', 'MONTHLY', 'WEEKLY', 'DAILY', 'HOURLY', 'MINUTELY', 'SECONDLY']


class ConvertibleRRule(rrule.rrule):
    # Subclass of the `rrule class that provides a sensible __str__()
    # method, outputting ical formatted rrules.
    # Combined from the patches in these dateutil issues:
    #  https://bugs.launchpad.net/dateutil/+bug/943512

我想定义一个不仅对文件Bremgarten_AV.status有效而且对所有.status文件都有效的任务。你知道伙计们怎么做？

Answer 1

import os
import fileinput

for _, _, files in os.walk("."):      # _, _, stands for not used elements (in triples)
    for name in files:
        if name.endswith((".status")):
            for line in fileinput.FileInput(name, inplace=1):
                line = line.replace("processing","upload")
                print line

Answer 2

您也可以尝试这样做以避免在不需要的文件上循环（即不以'.status'结尾）：

import os
import fileinput

# list of all your files in your path
list_files = [f for f in os.listdir(path) if f.endswith(".status")]

for f in list_files:
    for line in fileinput.FileInput(f, inplace=1):
        line = line.replace("processing","upload")

如何使用此格式设置数据任务？
