熊猫to_datetime返回错误的完美Python时间

Question

So I have a bunch of data that has timestamps in python epoch time format, however using this to_datetime() function returns ValueError: unconverted data remains: 00

Here's the code

import pandas as pd

print pd.to_datetime('1451080800', format='%Y%m%d')

What's going wrong here ?

Answer 1

Since you say it is epoch time, I think you want this:

In [44]: pd.to_datetime(int('1451080800'), unit='s')
Out[44]: Timestamp('2015-12-25 22:00:00')

Note the int(..) around the string. When specifying a unit (epoch is in seconds since 1970), the argument needs to be an integer.
