A function is a device that groups a set of statements so they can be run more than once in a program. Coding an operation as a function makes it a generally useful tool, which we can use in a variety of contexts.

def name(arg1, arg2,... argN):

statements

Functions can have an optional return statement.

def name(arg1, arg2,... argN):

...

return value

Example

Defining the function

# Get file name to save to

def GetFileFile():

dialog = SaveFileDialog()

filter = 'Text files (*.txt)|*.txt|All files (*.*)|*.*'

dialog.Filter = filter

dialog.Title = 'Save Parts'

dialog.FileName = design.ShortName

result = dialog.ShowDialog()

if result == DialogResult.OK:

return dialog.FileName

else:

return None

Calling the function

fileName = GetFileFile()
