将单词列表(数据帧内)转换为一组单词



在我的数据帧中,我有一列数据作为列表,如[细胞,蛋白质,表达],我想将其转换为一组单词,如细胞,蛋白质,表达式,它应该适用于数据帧的整个列。 请建议可能的方法。

试试这个

data['column_name'] = data['column_name'].apply(lambda x: ', '.join(x))

问题是df['Final_Text']不是一个列表,而是一个字符串。 首先尝试使用ast.literal_eval

import ast
from io import StringIO
# your sample df
s = """
,Final_Text
0,"['study', 'response', 'cell']"
1,"['cell', 'protein', 'effect']"
2,"['cell', 'patient', 'expression']"
3,"['patient', 'cell', 'study']"
4,"['study', 'cell', 'activity']"
"""
df = pd.read_csv(StringIO(s))
# convert you string of a list of to an actual list
df['Final_Text'] = df['Final_Text'].apply(ast.literal_eval)
# use a lambda expression with join to keep the text inside the list
df['Final_Text'] = df['Final_Text'].apply(lambda x: ', '.join(x))
    Unnamed: 0      Final_Text
0      0            study, response, cell
1      1            cell, protein, effect
2      2            cell, patient, expression
3      3            patient, cell, study
4      4            study, cell, activity
