替换数据框行中的标记

Question

我有这种 Python pandas 数据框，第一行是列：

Gender,Age,Weight,Height
    Male, 55, (82), 180
    Female, 34,(55),167
    Female,44,(67),182
    Male,81,(73),175
    Male,44,34,(87),185

如何去掉重量栏中的“()”标记？

Answer 1

使用矢量化的str.replace 删除括号：

In [189]:
df['Weight'] = df['Weight'].str.replace('[\(\)]','')
df

Out[189]:
   Gender  Age Weight  Height
0    Male   55     82     180
1  Female   34     55     167
2  Female   44     67     182
3    Male   81     73     175
4    Male   44     87     185
