Is python case sensitive?

Question

I watched some of code in Capital Letter and some in small letters. so is it case sensitive or not?

Answer 1

yes , mostly programming languages are case sensitive except SQL, Pascal, fortran etc

Answer 2

yes .perfectly sensitive

Answer 3

yes, if you make a variable in lower case and write after just one letter in capital letter you will have an error.
var and Var are different in python.

exemple.
var = 1
print (Var)

var= 1
Var= 2
add1 = var + var
add 2 = var + Var

print(add1)
>> 2

print (add2)
>>3
