python - 如何导入列表？ ( python )

Question

我是Python的新手。（我正在研究一周左右）
我正在尝试将文件导入为列表，然后从中选择一个随机词以在循环中使用它。我不太确定该怎么做！提前致谢

Answer 1

这是广义形式的答案：

f = open("path/to/file", "r") # opens the file as read-only
content = f.read() # there are easier ways to do this, but....
### do whatever you're doing here....
f.close() # MAKE SURE YOU CLOSE FILES when you're done with them
# if you don't, you're asking for memory leaks.

您也可以使用上下文管理器，但阅读起来有些困难：

with open("path/to/file","r") as f:
    content = f.read() # again, this is not the BEST way....
    ### do stuff with your file
# it closes automatically, no need to call f.close()

在文件操作之外，这是字符串->列表内容：

"a,b,c,d,e,f,g".split(',')
-> ['a','b','c','d','e','f','g']
# str.split creates a list from a string, splitting elements on
# whatever character you pass it.

这是 random.choice：

import random

random.choice(['a','b','c','d','e','f','g'])
-> 'c' # chosen by fair dice roll, guaranteed to be random! ;)
# random.choice returns a random element from the list you pass it
