我想使用Python将所有文本文件从一个文件夹移动到另一个文件夹.我找到了这段代码:

import os, shutil, glob

dst = '/path/to/dir/Caches/com.apple.Safari/WebKitCache/Version\ 4/Blobs '
try:
    os.makedirs(/path/to/dir/Tumblr/Uploads) # create destination directory, if needed (similar to mkdir -p)
except OSError:
    # The directory already existed, nothing to do
    pass

for txt_file in glob.iglob('*.txt'):
    shutil.copy2(txt_file, dst)

我希望它移动文件Blob夹中的所有文件.我没有收到错误,但它也没有移动文件.

我用for循环编写了一些代码.现在我想在执行循环一次后停止for循环.这是for循环:

for table in tables: #reason for it to do it 12x

    for tr in table.find_all("tr"):
        firstTd = tr.find("td")
        if firstTd and firstTd.has_attr("class") and "indent" in firstTd['class']:
            values = {}
            tds = tr.find_all("td")
            maxVal = tds[1].find("span", class_="wx-value")
            avgVal = tds[2].find("span", class_="wx-value")
            minVal = tds[3].find("span", class_="wx-value")
            if maxVal:
                values['max'] = maxVal.text
            if avgVal:
                values['avg'] = avgVal.text
            if minVal:
                values['min'] = minVal.text
            if len(tds) > 4:
                sumVal = tds[4].find("span", class_="wx-value")
                if sumVal:
                    values['sum'] = sumVal.text
            scrapedData = {}
            scrapedData[firstTd.text] = values
            weatherdata.append(scrapedData) …
