在python中删除行逗号

Question

我有一个看起来像这样的数据集：

Id          Product                   Age
001         soup,macaroni,             23
002         bread,milk,butter,         18
003         Bread,                     20

我想删除每个产品末尾的逗号，使其看起来像这样：

Id          Product                   Age
001         soup,macaroni             23
002         bread,milk,butter         18
003         Bread                     20

Answer 1

使用str.rstrip(",")

例如：

import pandas as pd
df = pd.DataFrame({"Product": ["soup,macaroni,", "bread,milk,butter,", "Bread,"]})
df["Product"] = df["Product"].str.rstrip(",")
print(df)

输出：

             Product
0      soup,macaroni
1  bread,milk,butter
2              Bread

Answer 2

让我们假设您的数据框为df。

执行以下操作

df["Product"] = df["Product"].apply(lambda x:x.strip(","))

Answer 3

可以str.slice直到最后一个值

df.Product.str.slice(0, -1)


0        soup,macaroni
1    bread,milk,butter
2                Bread
Name: Product, dtype: object
