" how to count the string in list as - lst=('abcdefgabc')". output should be a=2, b=2, c=2, d=1, e=1, f=1, g=1

Question

Trying to count the count of string where lst=('abcdefgabc')

lst=('abcdefgabc')
for i in lst:
    lst.count(i)
    print(i,(lst.count(i)))

output should be a=2, b=2, c=2, d=1,e=1,f=1,g=1

if you need the `=`, just add it as one more arg in the `print` function — rafaelc, Sep 13 '19 at 18:35

Side-note: Those parens around your string are pointless; `lst = 'abcdefgabc'` would mean the same thing, and not risk confusing people (e.g. with the name `lst`, I skimmed over it reading it as `list('abcdefgabc')` and thought you were pointlessly converting to `list`, rather than assigning a string to the name `lst`). — ShadowRanger, Sep 13 '19 at 20:15

Is this what you are looking for?

lst=('abcdefgabc')
new_list = []
for i in lst:
    a = i+"="+str((lst.count(i)))
    new_list.append(a)
b = sorted(set(new_list))
print(b)
for x in b:
    print(x)

Output:

['a=2', 'b=2', 'd=1', 'c=2', 'f=1', 'e=1', 'g=1']
a=2
b=2
d=1
c=2
f=1
e=1
g=1

There is no need for two `lst.count(i)`'s. Edit: There is no need for **three** `lst.count(i)`s. Count it once and store it as a local variable if you need it later in the loop. This is looping over `lst` `3*len(lst)` times. 3 times for each element. – SyntaxVoid supports Monica Sep 13 '19 at 18:40
Thank you so much, however we don't required the output double. eg. a=2 is showing twice. It should be displayed once. – PP Sinha Sep 13 '19 at 18:47
Edited! I hope this works well for you now. – Celius Stingher Sep 13 '19 at 18:59

Great Thanks to you. Yes that was the same which I was looking for. :) – PP Sinha Sep 13 '19 at 19:43

@PPSinha if this solves your problem, please mark it as the accepted answer! – SyntaxVoid supports Monica Sep 13 '19 at 19:48

Note that the OP seemed to want the output in order; changing `list(set(new_list))` to `sorted(set(new_list))` would accomplish that. Without sorting, the output order will actually vary from run to run (due to hash salting). – ShadowRanger Sep 13 '19 at 20:18
True, thanks for your suggestion, I edited my answer to contemplate it. – Celius Stingher Sep 13 '19 at 20:26
