Python 删除列中大于1的所有空格

我有一段适用于字符串的代码，但需要将其应用于列。有什么想法吗

foo = "hey     how are \n you doing today?"
foo = " ".join(foo.split())

输出：

print(foo)
hey how are you doing today?

如何在pandas中的整列文本中应用此选项？

您可以使用

str.replace

df = pd.DataFrame({'col':['how  are you?', 'This is a good   example']})
df['col'] = df['col'].str.replace('\s{2,}', ' ')


    col
0   how are you?
1   This is a good example
