Question

这是一个非常基本的问题，但是在Visual Studio中，我想将一堆名称转换为字符串数组。对于100多个名称，我将如何快速做到？

当前我的py文件：

Owen
Dylan
Luke
Gabriel
Anthony
Isaac
Grayson
Jack
Julian
Levi

我希望它看起来像什么

["Owen",
"Dylan",
"Luke",
"Gabriel",
"Anthony",
"Isaac",
"Grayson",
"Jack",
"Julian",
"Levi",
]

Answer 1

您可以打开文件并轻松读取其所有行：

with open('names_file.txt', 'r') as fp:
    names = fp.readlines()

print(names)

在read mode中打开文本文件并读取所有行，每一行将是names列表中的一项。

Answer 2

只需打开文件并将其分配给数组变量

with open('names_file.txt', 'r') as fp:
names = fp.read().splitlines()  #splitlines removes /n from each array element
print(names)

以r模式打开文件，并将字符串中的每一行分配给变量name

Answer 3

如果在与您提供的示例相同的文件中将名称列表转换为Python列表，则可以尝试以下操作：

names = []

with open('names.py', 'r') as inFile:
    names = [name for name in inFile]

with open('names.py', 'w') as outFile:
    outFile.write('[')
    for name in names:
        finalName = "\"" + name + "\""
        outFile.write(finalName.replace('\n','') + ',\n')
    outFile.write(']')

输出：

["Owen",
"Dylan",
"Luke",
"Gabriel",
"Anthony",
"Isaac",
"Grayson",
"Jack",
"Julian",
"Levi",
]

请注意，由于最后一个逗号，以上内容不是有效的Python列表。如果要创建有效列表，可以使用以下内容：

names = []

with open('names.py', 'r') as inFile:
    names = [name for name in inFile]

with open('names.py', 'w') as outFile:
    newNames = ["".join(["\"",name,"\""]).replace("\n","") for name in names]
    outFile.write('[')
    outFile.write(",\n".join(newNames))
    outFile.write(']')

输出：

["Owen",
"Dylan",
"Luke",
"Gabriel",
"Anthony",
"Isaac",
"Grayson",
"Jack",
"Julian",
"Levi"]
