How to access the string stored in the variable? (Python)

hope this fix your issue Since my last question was rather poorly worded, here is a different question that will provide me the same benefits! , You can create a variable in the module namespace like so
code :
new_set_name = 'buffalo'
globals()[new_set_name] = set()
import os
print(os.__dict__)
os.__dict__[new_set_name] = set()
setattr(os, new_set_name, set())

this one helps. OK, so your problem seems to be that your input string is not valid JSON. Here is an excerpt I cut out from the input you added to your question:
code :
{"source":"\\u003ca href="http:\\/\\/twitter.com\\/download\\/iphone"
  rel="nofollow"\\u003eTwitter for iPhone\\u003c\\/a\\u003e"}
{"source":"<a href="http:\\/\\/twitter.com\\/download\\/iphone""}
{"source":"<a href=\'http:\\/\\/twitter.com\\/download\\/iphone\'"}

I wish this help you Make sure your key don't include the delimiter '\n' included by bytes.ReadString():
(and more generally, don't ignore the return values, especially the errors)
code :
package main

import "bufio"
import "fmt"
import "os"

func main() {
    table := make(map[string]string)

    table["key1"] = "val1"
    table["key2"] = "val2"
    table["key3"] = "val3"

    fmt.Println("Enter a key (followed by Return):")
    reader := bufio.NewReader(os.Stdin)
    input, err := reader.ReadString('\n')
    if err != nil {
        panic(err)
    }

    val, ok := table[input]
    fmt.Println("val for key '" + input + "' = '" + val + "'(" + fmt.Sprintf("%v", ok) + ")")
}
'key2
'
input = strings.TrimRight(input, "\r\n")
Enter a key (followed by Return):
val for key 'key2' = 'val2'(true)

I think the issue was by ths following , I performing concatenation of multiple variables to a string and trying to store it in a list. I want the list to have the string but when i append the list in a loop, the value on the list is shown as tuple. Please help, New to python :) , First, this code:
code :
( key +' ' +' =', amount1+' ' +' /',amount2+' ' +' /',pincrease)
message = f'{key} = {amount1} / {amount2} / {pincrease}'
mylist.append(message)
