How to "Import"?
STEP 1 - Create a folder with any name you want.
STEP 2 - Now open that folder with any "Code Editor" you prefer. In my case I am using "Visual Studio Code". 👇👇
STEP 3 - Then , create a file with (.py) extension . 👇👇
STEP 4 - Create another file where you want to import stuff but these both files must be exist in same folder. 👇👇
STEP 5 - As you know that I have now two files which are A1 & A2 . Now , let's create a variable in A1 let's see how I can import it. 👇👇
STEP 6 - To import make sure that you have write "Import" keyword and the file name which you want to "Import' in that particular file where you actual want to use any function , class or variable. Like here in my case I want to use "x" which is present in A1 and I want to use it in A2. 👇👇
STEP 7 - Now A1 is "imported" let's try to print "x". 👇👇
STEP 8 - Ohh! 😲 There is an error while printing but why? Have I made any mistake NO! 🤔 Why I am unable to access the element of A1 ??
👉 I am facing this issue because I should write like this "print(A1.x)" this to print element of A1. 👇👇
STEP 9 - Now Everything is working fine...........😃😃
