collections.Counter lets you find the most common
# collections.Counter lets you find the most common
# elements in an iterable:
>>> import collections
>>> c = collections.Counter('helloworld')
>>> c
Counter({'l': 3, 'o': 2, 'e': 1, 'd': 1, 'h': 1, 'r': 1, 'w': 1})
>>> c.most_common(3)
[('l', 3), ('o', 2), ('e', 1)]
How do I calculate the difference in days for the following datetime in Python?
2018-01-01 15:00:00
2018-01-05 15:00:00
from datetime import datetime
datetime_fmt = '%Y-%m-%d %H:%M:%S'
date1 = datetime.strptime('2010-01-01 17:31:22', datetime_fmt )
date2 = datetime.strptime('2010-01-03 17:31:22', datetime_fmt )
days_diff = (d2-d1).days
print (days_diff)
