list(df)
list(df)方法可以直接获得df的列名
import numpy as npimport pandas as pddf = pd.DataFrame(data=[{"A":"one", "B":1, "C":11}, {"A":"two", "B":2, "C":22}])
| A | B | C | |
|---|---|---|---|
| 0 | one | 1 | 11 |
| 1 | two | 2 | 22 |
columns_list = list(df)print(columns_list)["A","B","C"]columns_list = str(list(df)).replace("[", "(").replace("]", ")")print(columns_list)("A","B","C")
一般来说可以用在选择数据 - df[][] - df[选择指定列][筛选条件]
