For loop with Python - using ints instead of datetime -


i have datascience task requires getting historical weather data. have looked @ wunderground.com api example structured so:

http://api.wunderground.com/api/d23ac65706dbf6dd/history_yyyymmdd/q/ca/san_francisco.json

therefore, when attempting build dataset need first day of year last day of year, can't with:

    20140101     20140102     20140103     ...     20141229     20141230     20141231

the thing can come is:

for m in range(1, 13):     d in range(1, 32):          r = requests.get("http://api.wunderground.com/api/0def10027afaebb7/history_2014'+str(m)+'/'+str(d)+'/q/mexico/mexico_city.json")         data = r.json()

but won't work. how go in python?

here minimal example demonstrates how iterate on actual dates:

>>> import datetime >>> start = datetime.date(2014, 1, 1) >>> end = datetime.date(2014, 1, 5) >>> while start <= end:     print start.strftime('%y%m%d')     start += datetime.timedelta(days=1)   20140101 20140102 20140103 20140104 20140105

see the datetime documentation more information.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
