Mixed string,Integer input variable issue

[snippsat]

Other option is to make a dictionary,can just use your code and add dict().
Also showing f-string so can avoid code like "line_" + str(line).

# Make dictionary
line_record = dict(
    Line_1 = "Choice_C",
    Line_2 = "Choice_B",
    Line_3 = "Choice_A",
    )

line = input("pick a line number: ")
result = line_record.get(line, 'No record of that input')
print(result)
print('--------------')
# Example of f-string
print(f'Input was <{line}> with result of <{result}>')

Output:
λ python line_code.py                                           
pick a line number: Line_2                                      
Choice_B                                                        
--------------                                                  
Input was <Line_2> with result of <Choice_B>                    
                                                        
λ python line_code.py                                           
pick a line number: Line1000                                    
No record of that input                                         
--------------                                                  
Input was <Line1000> with result of <No record of that input>
