The code below is a program that reads the specified text file (ave.txt) and produces the average temperature.

Current State Code:

 path="ave.txt"
sum = 0.0
a = 0
with open(path, "r") as f:
    For lin f:
        l = l. strip()
        b=l.split(',')
        iflen(b) == 1:
            name = (b[0].strip('"')
        iflen(b) == 2:
            sum+=float(b[1].trip('"))
            a + = 1

The average temperature for print(f"{name} is {sum/a} degrees.")

ave.txt

"Tokyo"
"January", "-3.6"
"February", "-3.1"
"March", "0.6".
"April", "7.1".
"May", "12.4".
"June", "16.7".
"July", "20.5".
"August", "22.3".
"September", "1
"October", "11.8".
November, 4.9
"December", "-0.9"

It is a program that reads a file and produces an average temperature.
So if you look at the b of this expression, you'll see this:

b results:

['Tokyo']
["January", "-3.6"]
["February", "-3.1"]
["March", "0.6"]
["April", "7.1"]
["May", "12.4"]
["June", "16.7"]
["July", "20.5"]
["August", "22.3"]
["September", "18.1"]
["October", "11.8"]
["November", "4.9"]
["December", "-0.9"]

What should I do if I want to go from this state to the following state?

Expected results:

January: -3.6 degrees↩
February: -3.1 degrees ↩
March: 0.6 degrees ↩
April: 7.1 degrees ↩
May: 12.4 degrees ↩
June: 16.7 degrees ↩
July: 20.5 degrees ↩
August: 22.3 degrees ↩
September: 18.1 degrees ↩
October: 11.8 degrees ↩
November: 4.9 degrees ↩
December: -0.9 degrees ↩

I'd like to erase ''' and put : in place of ','.
Only the moon and temperature are displayed, not the first line of Tokyo.

The extension is .txt, but the data content seems to follow the format CSV.

Rather than just using a number of basic lines, you might want to consider using the standard csv module.

You can do it like this.

import csv
path = 'ave.txt'
#### sum = 0.0
#### a = 0
with open(path, 'r', newline=', encoding='utf-8')ascsvfile:
    spamreader=csv.reader(csvfile, delimiter=',',quotechar='")
    name=next(spamreader)[0]
    For row inspamreader:
        #### sum+=float(row[1])
        #### a + = 1
        print(f'{row[0]}:{row[1]} degrees')

#### The average temperature for print(f"{name} is {sum/a} degrees.")

Comments are made in ### for the parts that are not required for the "Expected View Results" of the original source.
Also, the display results look like a full-width colon :, so print() specifies it.

encoding= should be modified according to the contents of the file.
delimiter= and quotechar= are the same as the default values, so you don't have to specify them, but short usage examples on the reference page: changed and used them, so I put them back in place.
