Import external class files using Python

GenerallyCodeThe code used to call a class to create an object is rarely stored in the same file. This problem occurs when one file needs to call another independently stored class file to create an object. There are few introductory books and online textbooks mentioned in this regard. The following example shows the implementation method:

T1.py:

# Here is the file defining the class CAL: def sum (self, a, B): return a + B def Cha (self, a, B): return a-B

T2.py:

# Here is the file for creating the object from T1 import Cal # The syntax format of the import class is: From file name import class name c = CAL () B = C. cha (1, 2) print (B)
