Why doesn't this code give x+2 answer as we have reassigned the value of x ?

Question

x = 7
x = x + 2
print(x)

Answer 1

In order to print `x+2` you'll need to assign a string instead of result of arithmetic expression.

x=7 # this assign 7 to variable x

x=x+2 #this means add 2 to current value of x and assign the result to x.

which is similar to x=7+2
x=9

thus you get output 9.

as mentioned earlier for printing `x+2` you'll need to quote it and then assign.

x="x+2"
print(x)

if you review your course or search on interbet it'll benifit you more than my answer.
