Question

I would like to add numbers in a dictionary, cumulative so it will add the keys of the dictionary.

x = ' '
dict = {}
list = []
while x != '':
x = raw_input('Enter line:')
p = x.split(' ')
if x != '':
    list.append(p)
result = sum(list, [])
result = result
num = []
for a in result:
for n in dict:
    p = a.count(a)
    l = a
    if n == l:
        l += l
dict[a] = p
print dict

raw_input('')

I would like “dict” to consist of the words from the input and the amount of times that they were entered.
Thanks

use Counter:

from collections import Counter
x=raw_input('enter line\n')
if x.strip():
    x=x.split()
    count=Counter(x)
    dic=dict(count)
    print dic
else:
    print 'you entered nothing'

output:

>>> 
enter line
cat cat spam eggs foo foo bar bar bar foo
{'eggs': 1, 'foo': 3, 'bar': 3, 'cat': 2, 'spam': 1}

and without using Counter(which is not recommended) you can use sets:

dic= {}
x = raw_input('Enter line:')
if x.strip():
    p = x.split()
    for x in set(p):   #set(p) contains only unique elements of p
        dic[x]=p.count(x)
    print dic
else:
    print 'you entered nothing'

output:

>>> 
Enter line: cat cat spam eggs foo foo bar bar bar foo
{'eggs': 1, 'foo': 3, 'bar': 3, 'cat': 2, 'spam': 1}
