'''
In python, you can use try, except and finally to catch errors to keep
running your code even when you run into an error.

try:
	# insert code
except SpecificError:
	# code that will run if the code in 'try' doesn't work
finally:
	# always runs this code, error or not
'''

try:
  myVar = 10 / 0 # runs into an error
except ZeroDivisionError as error:
  print(error) # prints error to user
finally:
  print('Finished try, except, finally') # always prints
