Short hands of loops and conditions

#shorthand.py
result = []
for x in [1,2,3]:
    for y in [3,1,4]:
        if x != y:
            result.append((x, y))
print(result)

result=[(x, y) for x in [1,2,3] for y in [3,1,4] if x != y]
print(result)

Output
[(1, 3), (1, 4), (2, 3), (2, 1), (2, 4), (3, 1), (3, 4)]
[(1, 3), (1, 4), (2, 3), (2, 1), (2, 4), (3, 1), (3, 4)]

Using time module

The time module provides the current date and time using time() function The time.time() returns the number of second elapsed from 1/1/1970 12:00 am till current date and time called as ticks >>> import time >>> time.time() 1522211915.914467 We can also convert these ticks into actual date and time using function time.localtime() >>> time.localtime(time.time()) time.struct_time(tm_year=2018, tm_mon=3, tm_mday=28, tm_hour=10, tm_min=10, tm_sec=0, tm_wday=2, tm_yday=87, tm_isdst=0) It returns a structure having different fields for date and time which we can convert into date or time format >>> t=time.localtime(time.time()) >>> currentdate='%02d-%02d-%d' % (t.tm_mday,t.tm_mon,t.tm_year) >>> currentdate '28-03-2018' >>> currenttime='%02d-%02d-%02d' % (t.tm_hour,t.tm_min,t.tm_sec) >>> currenttime '10-12-05' We can also use this structure inside the functions and ...
