Why can't I see the result of the function when I use range()? I want to create a range of numbers where each the number will be evaluate in "colla" function. But range doesn't work with "colla"
def colla(num):
fin = []
while num != 1:
if num % 2 == 0:
num = num // 2
fin.append(0)
elif num % 2 == 1:
num = 3 * num + 1
fin.append(1)
counter = []
for Z in fin:
if Z == 0:
counter.append(Z)
return ("{:.0%}".format((len(counter)/len(fin))))
for i in range(5):
print(colla(i)) # here I have a problem!
Your colla() function requires input numbers of 2 and above.
Try this:
for i in range(2,6):
print(colla(i))
Please be aware that calling colla(0) will result in an infinite loop, or rather "out of memory" when fin fills up with 0s. Also calling colla(1) results in a ZeroDivisionError because fin will be an empty list.
