# Incremental Count and it's position in Python [closed]

I have a requirement to get incremental counts. I am new to Python so please help me.

I have tried below:

Testword = 'foo boo'
letters = 'abcdefghijklmnopqrstuvwxyz'
for key in Testword:
print key, Testword.count(key)


Results :

f 1
o 4
o 4
1
b 1
o 4
o 4


I would like to get incremented count output in the same input order like

f=1
o=1
o=2

b=1
o=3
o=4

This question appears to be off-topic. The users who voted to close gave this specific reason:

• "Code not implemented or not working as intended: Code Review is a community where programmers peer-review your working code to address issues such as security, maintainability, performance, and scalability. We require that the code be working correctly, to the best of the author's knowledge, before proceeding with a review." – Peilonrayz, t3chb0t, Toby Speight, alecxe, Graipher
If this question can be reworded to fit the rules in the help center, please edit the question.

What you are looking for is the number of occurences until the position, you are currently looking at. Using Testword[:pos+1], you can take the substring until the current position. Hence:

testword = 'foo boo'
letters = 'abcdefghijklmnopqrstuvwxyz'
for pos, key in enumerate(testword):
print(key, testword[:pos+1].count(key))


Gives

f 1
o 1
o 2
1
b 1
o 3
o 4


Btw, please use python3, not python2.
