Since you're parsing a 12-hour time format, you will need %I instead of %H, otherwise the %p specifier has no effect.

pd.to_datetime("2018 - 07 - 07 04 - PM", format='%Y - %m - %d %I - %p')
Timestamp('2018-07-07 16:00:00')

When used with the strptime() function, the %p directive only affects the output hour field if the %I directive is used to parse the hour.
