Detailed explanation of the steps of Python variable assignment

This time I will bring you a detailed explanation of the steps for Pythonvariableassignment, what are the notes for Python variable assignment, the following is a practical case, one Get up and take a look.

>>> x = 12
>>> y= 13
>>> id(x)
>>> id(y)
>>> x = y
>>> id(x)
>>> id(y)

First assign the value of 12 to the x variable and 13 to the y variable. We use id (variable) to view the locations of x and y in the memory respectively. The above display is 1865402384 and 1865402416 respectively. Then after we set x = y, we checked their locations in memory and found that both x and y pointed to 1865402416. It can be seen that in python, the way we assign values ​​is different from C language. C language directly changes the value in the memory of x, while Python directly changes the pointer of x. This reminds me of pointer.

Let’s try it next and continue to enter the following code here

>>> y = 12
>>> id(y)
1865402384
