フォーマット集計はtimedelta

Question

[OK]をので、私はpandas pivot table documentationを見て、以下同様の質問している：私の問題は、出力timedeltasたときに集約されるしかし

• String formatting of timedeltas in pandas
• Pandas Pivot Table aggfunc in HOURS:MINUTES format

彼らは1 day 12:30:00のフォーマットを表示して、それを36:30:00と表示したいとします。これを行う方法はありますか？

CODE

pd.pivot_table(
    df, 
    index=["date","task_type"], 
    columns=["calendar"], 
    values="duration", 
    aggfunc=np.sum, 
    fill_value=timedelta(hours=0), 
    margins=True, 
    margins_name="TOTAL" 
) 

OUTPUT

Answer 1

を期待したが、私は0を実装してみてくださいapplyとソリューション：

def f(x): 
    ts = x.dt.total_seconds() 
    hours, remainder = divmod(ts, 3600) 
    minutes, seconds = divmod(remainder, 60) 
    return hours.abs().astype(int).astype(str).str.zfill(2) + ':' + \ 
      minutes.abs().astype(int).astype(str).str.zfill(2) 


df1 = df.apply(f) 
print (df1) 
calendar      Proj1 Proj2 Proj3 TOTAL 
date    task_type        
2017-04-03 15:30:00 c   00:00 00:00 00:00 00:00

...とapplymapを持つ：

def f(x): 
    ts = x.total_seconds() 
    hours, remainder = divmod(ts, 3600) 
    minutes, seconds = divmod(remainder, 60) 
    return ('{:02d}:{:02d}').format(int(hours), int(minutes)) 

df2 = df.applymap(f) 
print (df2)

サンプルのセットアップ：

N = 10 
np.random.seed(10) 
rng = pd.date_range('2017-04-03 15:30:00', periods=N, freq='3.5H') 
df = pd.DataFrame({'date': np.random.choice(rng, size=N), 
        'task_type': np.random.choice(list('abcde'), size=N), 
        'calendar': np.random.choice(['Proj1','Proj2','Proj3'], size=N), 
        'duration': np.abs(np.random.choice(rng, size=N) - 
             np.random.choice(rng, size=N)) }) 
#print (df) 



df = pd.pivot_table(
    df, 
    index=["date","task_type"], 
    columns=["calendar"], 
    values="duration", 
    aggfunc=np.sum, 
    fill_value=pd.Timedelta(hours=0),
