How to convert datetime in python

#How to convert datetime in python like below:

df.Start_Time

#         2016-02-08 00:37:08
#         2016-02-08 05:56:20


df.Start_Time = pd.to_datetime(df.Start_Time)

datetime convert python

# input: 07:40:01PM
# output: 19:40:01

# First System:

def timeConversion(s):
    period = s[-2:]
    time = s[:-2]
    hour = int(time[:2])
    
    if period == 'PM' and hour < 12:                
        time = str(hour + 12) + time[2:]

    if period == 'AM' and hour == 12:
        time = '00' + time[2:]
        
    return time
s = input()
print(timeConversion(s))

# second code and use to module:

"""
from datetime import*

    return datetime.strftime(datetime.strptime(s, "%I:%M:%S%p"), "%H:%M:%S")
if __name__ == '__main__':
    s = input()
    print(timeConversion(s))
    
"""

# 3rd code and not used module.
