how does the python interpreter assess a=b?

Question

does a=b mean that the value of b is now value of a OR the value of a is now the value of b ?
is the reading order of the interpreter from the right to left or from left to right?
for ex we have to swap two variables using a third one
let's say a=90
b=10 and assume c as the third variable
if the reading order is right to left then
c=a means the value of a is now equal to c ....going by the same convention the code for swapping will be
c=a
b=a
c=b but when I execute this both variables's value is same
Can somebody please explain this to me ?

Answer 1

a = 1
b = 2
a = b
print(a) #output is 2
c = a
b = a
c = b
print(c) #output is 2

hi shaleen agarwal,i hope that you have nice time,in each language when you want to swap two variable for example A=20 and B=23 ,you need the third variable for example C "Just as you said".
i want to say when you put it equal two variable in each language you should look at the code from right to left.
lets look at this code:
C=A; //form right to left fist C equal to A,"i mean at first A was 20 and when you put it equal A with C, C be 20"

A=B;//form right to left fist B equal to A,"i mean at first B was 23 and when you put it equal B with A, A be 23"

B=C;//form right to left fist C equal to B,"i mean at first C was 20 and when you put it equal C with B, B be 20"

by this code you swap two variable

i hope to help you,good luck

Answer 3

hi.
The assignment operator (a = b) initializes or updates the value of a with the value of b

Answer 4

a=b means that the value of b has been assigned to a
