我有带有数组列的熊猫数据框:
id,classes,text
71,`["performer_146", "performer_42"]`,`adipiscing urna. molestie `
72,["performer_42"],`a ligula odio elementum, neque suscipit. egestas Maecenas`
73,["performer_146"],`vestibulum orci nec vestibulum, ligula orci et mauris lobortis, et Aliquam`
74,["performer_0"],tincidunt non interdum nunc ultrices mi accumsan elementum arcu venenatis
75,`["performer_146", "performer_42"]`, orci elementum non finibus dolor. Cras
76,`["performer_42", "performer_146"]`,`mi lectus Maecenas eleifend neque amet, `
77,["performer_146"],` platea placerat. odio Morbi rutrum, eu Cras`
我阅读了这个 CSV 并将“类”列的值转换为数组:
import pandas as pd
import ast
df = pd.read_csv(filename, quotechar='`')
df['classes'] = df['classes'].apply(lambda x: ast.literal_eval(x))
现在我想在“类”值中选择带有“performer_0”的行。像这样:
df['performer_0' in df['classes']]
但是这段代码不起作用:
Traceback(最近一次调用最后一次):文件“d:\pyenv\pandas\lib\site-packages\pandas\core\indexes\base.py”,第 2657 行,在 get_loc return self._engine.get_loc(key) File 中pandas_libs\index.pyx",第 108 行,在 pandas._libs.index.IndexEngine.get_loc 文件 "pandas_libs\index.pyx",第 132 行,在 pandas._libs.index.IndexEngine.get_loc 文件 "pandas_libs\hashtable_class_helper.pxi" ,第 1601 行,在 pandas._libs.hashtable.PyObjectHashTable.get_item 文件“pandas_libs\hashtable_class_helper.pxi”,第 1608 行,在 pandas._libs.hashtable.PyObjectHashTable.get_item KeyError: False
我怎样才能做到这一点?
