如果 str1 in row of col==str in row of another col, set str1=str2 of third col
If str1 in row of col==str in row of another col, set str1=str2 of third col
我有一个合并的数据框,我想在其中检查 'profile' 列的行中包含的每个字符串与 'right_side' 列的行中的每个字符串。如果这两个字符串相等,我想用 'left_side' 列中的 str 替换 'profile' 列中的 str 。由于某种原因,我在这方面遇到了很多困难,并尝试了 .loc、dict、map 和 .at 方法,但必须缺少一个组件,每个组件都无法正常工作。这是数据框:
profile left_side right_side
DevOps Developer NaN NaN
Software Developer Software Development Developer Software Developer
Software Developer Software Development Developer Software Developer
Quality Assurance Quality Assurance Engineer Quality Assurance
非常感谢您的帮助!
df.loc[(df["Profile"]==df["right_side"]),"Profile"]=df["left_side"]
print(df)
Profile ... right_side
0 DevOps Developer ... NaN
1 Software Development Developer ... Software Developer
2 Software Development Developer ... Software Developer
3 Quality Assurance Engineer ... Quality Assurance
[4 rows x 3 columns]
这是你想要的吗?
这是我使用 lambda 的尝试:
data["profile"] = data.apply(lambda x: x[1] if x[0] == x[2] else x[0], axis=1)
