So you have edited it quite a bit since I started writing about conventions so I have started again.
First, your return statement is out of indentation, it should be indented into the output method.
def output():
a = "Hello"
data = // some operations
return data
Second, the convention in Python regarding class names is CamelCase, which means your class should be called "Connect". There is also no need to add the round brackets when your class doesn't inherit anything.
Third, right now you can only use "data" since only data is returned. What you can do is return both a and data by replacing your return statement to this:
return a, data
Then in your second file, all you have to do is write a_received, data_received = connect.output()
Full code example:
file1.py
class Connect:
def output():
a = "Hello"
data = "abc"
return a, data
file2.py
from file1 import Connect
a_received, data_received = Connect.output()
# Print results
print(a_received)
print(data_received)
Fourth, there are other ways to combat this, like create instance variables for example and then there is no need for return.
file1.py
class Connect:
def output(self):
self.a = "Hello"
self.data = "abc"
file2.py
from file1 import Connect
connection = Connect()
connection.output()
print(connection.a)
print(connection.data)
There is also the class variable version.
file1.py
class Connect:
def output():
Connect.a = "Hello"
Connect.data = "abc"
file2.py
from file1 import Connect
Connect.output()
print(Connect.a)
print(Connect.data)
Eventually, the "right" way to do it depends on the use.
