[英]Pandas Dataframe replace part of string with value from another column
[英]Pandas Replace part of string with value from other column
我有一个 dataframe (参见示例,因为敏感数据),带有一个完整的术语(字符串),一个包含完整术语和缩写(字符串)的文本片段(一个大字符串)。 我一直在努力解决如何用相应的缩写替换文本片段中的完整术语。 任何人都可以帮忙吗? 例子:
term text_snippet abbr
0 aanvullend onderzoek aanvullend onderzoek is vereist om... ao/
所以我想结束:
term text_snippet abbr
0 aanvullend onderzoek ao/ is vereist om... ao/
您可以使用apply
并用缩写替换术语:
df['text_snippet'] = df.apply(
lambda x: x['text_snippet'].replace(x['term'], x['abbr']), axis=1)
df
Output:
term text_snippet abbr
0 aanvullend onderzoek ao/ is vereist om... ao/
这是一个解决方案。 我编了一个简单的dataframe:
df = pd.DataFrame({'term':['United States of America','Germany','Japan'],
'text_snippet':['United States of America is in America',
'Germany is in Europe',
'Japan is in Asia'],
'abbr':['USA','DE','JP']})
df
Dataframe 之前的解决方案:
term text_snippet abbr
0 United States of America United States of America is in America USA
1 Germany Germany is in Europe DE
2 Japan Japan is in Asia JP
在每一行上使用 apply function:
df['text_snippet'] = df.apply(lambda row : row['text_snippet'].replace(row['term'],row['abbr']), axis= 1 )
Output:
term text_snippet abbr
0 United States of America USA is in America USA
1 Germany DE is in Europe DE
2 Japan JP is in Asia JP
