Subtracting two dates in python

0 votes
1,862 views

I would like to subtract two dates i.e I have entered a date into a textbox which is of type String like below

type(waitForObject(":VWAP Calculator_LCDateTextField"), "07/24/14")

I am capturing that date like below

Current = (waitForObject(":VWAP Calculator_LCDateTextField").text)

so, now I want to subtract the captured date with my current system date and get the difference in days. I tried many ways and see no success.

Someone please help?

Try the 'datetime' module:

 >>> from datetime import datetime
 >>> d = datetime.strptime("07/24/14", "%m/%d/%y")
 >>> d
datetime.datetime(2014, 7, 24, 0, 0)
 >>> diff = datetime.now() - d
 >>> diff.days
7

If you have the user-entered date in a string format, you can use datetime.strptime() to convert it into a datetime object, like so:

 from datetime import datetime
 user_date = datetime.strptime(user_input, "%m/%d/%y")

Get the current system date like this:

 now_date = datetime.now()

Subtract the two datetime objects to obtain a timedelta object:

 mydelta = now_date - user_date

Look at the days attribute to get the difference in days:

 mydelta.days

I have a list, songs, which I want to divide into two groups.
Essentially, I want:

new_songs = [s for s in songs if s.is_new()]
old_songs = [s for s in songs if not s.is_new()]

but I don't want to make two passes over the list. I could do:

new_songs = []
old_songs = []
for s in songs:
 if s.is_new():
 new_songs.append(s)
 else:
 old_songs.append(s)

Which works, but is klunky compared to the two-liner above. This seems like a common enough thing that I was expecting to find something in itertools which did this. I'm thinking something along the lines of:

matches, non_matches = isplit(lambda s: s.is_new, songs)

Does such a thing exist?

I'm trying to multiply two matrices that has different size.

import numpy as np

a = np.random.randn(4, 3)
b = np.random.randn(4, 1)

print a
print b

How should I multiply a and b so that the multipled matrix's size is 4*3?

I want to multiply matrix 'b' to each row of matrix 'a'.
So that if matrix a is
[[1, 2, 3],
[2, 3, 4]]
and b is
[[2],
[3]]
a*b is
[[2, 4, 6],
[4, 6 ,8]]

Plz help me, if possible, plz use numpy
