Python：代码未选取列表中的所有字符串值

Question

我创建了以下代码来创建多个文件夹

import os

Country = {"Albania - AL",
"Armenia - AM",
"Austria - AT",
"Bahrain - BH",
"Belarus - BY",
"Belgium - BE",
"Bulgaria - BG",
"Canary Islands - KY",
"Croatia - HR",
"Cyprus - CY",
"Czech Republic - CZ",
"Denmark - DK",
"Estonia - EE",
"Finland - FI",
"France - FR",
"Germany - DE",
"Greece - GR",
"Hungary - HU",
"Iceland - IS",
"Ireland - IE",
"Israel - IL",
"Italy - IT",
"Latvia - LV",
"Lithuania - LT",
"Luxembourg - LU",
"Malta - MT",
"Morocco - MA",
"Netherlands - NL",
"Norway - NO",
"Poland - PL",
"Portugal - PT",
"Romania - RO",
"Russian Federation - RU",
"Saudi Arabia - SA",
"Serbia - RS",
"Slovakia - SK",
"Slovenia - SI",
"South Africa - ZA",
"Spain - ES",
"Sweden - SW",
"Switzerland - CH",
"Turkey - TR",
"United Arab Emirates - AE",
"United Kingdom Of Great Britain And Northern Ireland - UK",
}

for x in Country:
    path = ("C:/Users/thrnma/Documents/VAT Reporting/" + x)

try:
    os.mkdir(path)
except OSError:
    print ("Creation of the directory %s failed" % path)
else:
    print ("Successfully created the directory %s " % path)

当我运行程序时，它只为沙特阿拉伯生成一个文件夹。我多次尝试运行ning 它，但它不会生成任何新文件夹。我假设我需要做一些类似循环的事情，但我不确定该怎么做（在 Python 仍然是新手）。提前谢谢你。

Answer 1

您没有将 "creating directory" 部分放入循环中。
这应该有效，尝试了解其中的区别：

import os

Country = {"Albania - AL",
"Armenia - AM",
"Austria - AT",
"Bahrain - BH",
"Belarus - BY",
"Belgium - BE",
"Bulgaria - BG",
"Canary Islands - KY",
"Croatia - HR",
"Cyprus - CY",
"Czech Republic - CZ",
"Denmark - DK",
"Estonia - EE",
"Finland - FI",
"France - FR",
"Germany - DE",
"Greece - GR",
"Hungary - HU",
"Iceland - IS",
"Ireland - IE",
"Israel - IL",
"Italy - IT",
"Latvia - LV",
"Lithuania - LT",
"Luxembourg - LU",
"Malta - MT",
"Morocco - MA",
"Netherlands - NL",
"Norway - NO",
"Poland - PL",
"Portugal - PT",
"Romania - RO",
"Russian Federation - RU",
"Saudi Arabia - SA",
"Serbia - RS",
"Slovakia - SK",
"Slovenia - SI",
"South Africa - ZA",
"Spain - ES",
"Sweden - SW",
"Switzerland - CH",
"Turkey - TR",
"United Arab Emirates - AE",
"United Kingdom Of Great Britain And Northern Ireland - UK",
}

for x in Country:
    path = ("C:/Users/thrnma/Documents/VAT Reporting/" + x)

    try:
        os.mkdir(path)
    except OSError:
        print ("Creation of the directory %s failed" % path)
    else:
        print ("Successfully created the directory %s " % path)

Answer 2

只需修复 try 块的缩进。就是这样。

应该是这样的：

for x in Country:
    path = ("C:/Users/thrnma/Documents/VAT Reporting/" + x)

    try:
        os.mkdir(path)
    except OSError:
        print ("Creation of the directory %s failed" % path)
    else:
        print ("Successfully created the directory %s " % path)

Answer 3

将 os.mkdir(path) 部分放在 for 循环中。

for x in Country:
    path = ("C:/Users/thrnma/Documents/VAT Reporting/" + x)

    try:
        os.mkdir(path)
    except OSError:
        print ("Creation of the directory %s failed" % path)
    else:
        print ("Successfully created the directory %s " % path)

Python: Code is not picking up all string values in list

python

string

directory

list

subdirectory
