[Solved] Positive and negative numbers

by


See let’s take a list , say sample_list

sample_list = [1, 5, -9, 6, 7, -7, -2, -4, 2, 3]

Or

sample_list = []
while True:
    a = int(raw_input())
    if a==0: break
    else:sample_list.append(a)

Now, To get the length of list 

sample_list_length = len(sample_list)

where len() is a inbuilt function which returns the length of any iterable object like strings,lists,etc.

positive_number = 0
negative_number = 0
for dummy_number in sample_list:
    if dummy_number>=0:
        positive_number+=1
    else:
        negative_number+=1

print "There are",positive_number,"positive numbers"
print "There are",negative_number,"negative numbers"
print "There are",sample_list_length,"total numbers"
