Use dictionaries. See this example

Or, if you want to use it with variables defined in the global scope, the globals() function returns a dictionary having all the variables stored with their values

Answer 7

Atul nope

read the note : I need without using eval()

Answer 8

b="world"
a="hello"

x=a+" "+b

print(x)

Answer 9

Try making x a list
x = [a, b]
Then your loop executes.
Output:
["hello", "world"]
If you want it to be printed as a string, the join() method comes in handy.
Syntax:
(" ".join(sen))
Note the space in the quote.
Hope this helps.
