dataframe. 매달 모든 정보를 입수해야합니다. ! 그리고 언젠가 달에 지금의 경우 = 0, I는 다음과 같이 표를 얻을 필요가 달 1로 인쇄하지만, 열 이름은 달이며, 값은 될 수 0 또는 1

Answer 1

난 당신이 to_period를 사용할 수 있다고 생각 :

df['member_id'] = df.member_id.astype(str) 
df.set_index('member_id', inplace=True) 
df = df.unstack().reset_index(name='val').rename(columns={'level_0':'date'}) 
df['date'] = pd.to_datetime(df.date).dt.to_period('m').dt.strftime('%Y-%m') 
#df = (df != 0).astype(int) 
df = df.groupby(['date','member_id'])['val'].sum() 
df = (df != 0).astype(int).unstack(0) 
print (df)
