我正在尝试将MM:SS格式的两列加在一起。我尝试使用to_timedelta,但出现错误“预期的hh:mm:ss格式”
答案 0 :(得分:4)
在to_timedelta
之前的零小时内将00:
添加到两列:
df = pd.DataFrame({'col1':['10:20','32:32','21:10'],
'col2':['13:56','22:02','01:30']})
df['new'] = pd.to_timedelta('00:' + df['col1']) + pd.to_timedelta('00:' + df['col2'])
print (df)
col1 col2 new
0 10:20 13:56 00:24:16
1 32:32 22:02 00:54:34
2 21:10 01:30 00:22:40
