This tutorial will show how to use variables from one Python file in another. The first step in using another Python file is to use the built in keyword import . Import is used to import Python libraries modules. Here is a List of useful keywords
When using import , the file being imported will be executed when the Python file importing it is ran.
For this example, there are two Python Files the first file is named Main.py and the file being imported is named Second.py
Main.py
import Second
#printing X var from Second
print(Second.X)
In the Main.py file the Second file will be imported. Then the X variable from the will be printed out.
Second.py
X= 5
try:
# If X is Greater than 5
if X> 3:
print("Greater Value")
# X less than five
else:
print("Nope")
#
finally:
print("Run Complete")
The Second file consist of a try statement that checks if the X variable is greater than 3.
Note: the finally will always run.
Output :
Greater Value
Running
5
