没有找到一个好的正则表达式模式来以正确的顺序替换字符串(python)

Not finding a good regex pattern to substitute the strings in a correct order(python)

我有一个字符串格式的列名列表,如下所示:

lst = ["plug", "[plug+wallet]", "(wallet-phone)"]

现在我想使用正则表达式将 df[]" ' " 添加到每个列名,我这样做了,当列表具有 (wallet-phone) 这种字符串时,它给出了一个像这样输出 df[('wallet']-df['phone')]。我怎么会这样 (df['wallet']-df['phone']), 是不是我的模式错了。请参考以下:

import re
lst = ["plug", "[plug+wallet]", "(wallet-phone)"]
x=[]
y=[]
for l in lst: 
    x.append(re.sub(r"([^+\-*\/'\d]+)", r"''", l))
    for f in x:    
        y.append(re.sub(r"('[^+\-*\/'\d]+')", r'df[]',f))

print(x)
print(y)

给出:

x:["'plug'", "'[plug'+'wallet]'", "'(wallet'-'phone)'"]
y:["df['plug']", "df['[plug']+df['wallet]']", "df['(wallet']-df['phone)']"]

模式有误吗? 预期输出:

x:["'plug'", "['plug'+'wallet']", "('wallet'-'phone')"]
y:["df['plug']", "[df['plug']+df['wallet']]", "(df['wallet']-df['phone'])"]

我也试过 ([^+\-*\/()[]'\d]+) 这种模式,但它并没有避免 () or []

查找单词并将其包含在字典参考中可能更容易:

import re
lst = ["plug", "[plug+wallet]", "(wallet-phone)"]

z = [re.sub(r"(\w+)",r"df['']",w) for w in lst]

print(z)
["df['plug']", "[df['plug']+df['wallet']]", "(df['wallet']-df['phone'])"]
