I could use some help with this problem. I need to make a function that creates a dictionary with 4 parameters and a key that increase every entry of this dictionary. So far i have this:
def create_db(temp, rain, humidity, wind):
weather = {}
n = 0
for i in (temp, rain, humidity, wind):
n = n + 1
weather[n] = (temp, rain, humidity, wind)
return weather
temp = [1, 5, 3]
rain = [0, 30, 100]
humidity = [30, 50, 65]
wind = [3, 5, 7]
weather = create_db(temp, rain, humidity, wind)
print(weather)
problem with this is that it prints:
{1: (1, 0, 30, 3), 2: (1, 0, 30, 3), 3: (1, 0, 30, 3), 4: (1, 0, 30, 3)}
It only put the first value for the list in all for them.
What am I doing wrong?
>Solution :
temp, rain etc are lists. You need to reference the element in each list – i.e.
weather[n] = (temp[n], rain[n], humidity[n], wind[n])
You also don’t mean for i in (temp, rain, humidity, wind) – this will be 4, because there are 4 list variables there. Instead use the length of one of the lists, e.g.:
for n in len(temp):
That way you also don’t need to increment n.
