How to combine strings and make a int to print a value already set

Question

I want to combine this 2 strings and make a "path" for object800 to print the value

x = 'object'

y = '800'


object800 = 1000


a = (x + y)

print(int(a)) # i want to print 1000

Answer 1

You should use globals:

x = 'object'
y = '800'

object800 = 1000

print(globals()[x + y])
# Outputs 1000

Note that this won't work inside a function, for example:

x = 'object'
y = '800'

def func():
    object800 = 1000
    print(globals()[x + y]) 
    # Raises KeyError: 'object800'
    
func()

If that's the case, you should use a different approach:

x = 'object'
y = '800'

def func():
    object800 = 1000
    
    varname = x + y
    print(globals()[varname] if varname in globals() else locals()[varname]) 
    # Outputs 1000
    
func()

Answer 2

You should use eval.

x = 'object'
y = '800'
object800 = 1000
a = eval(x + y)
print(a)
