'''
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

# Try and Except in python are for taking care of errors
# which may occur at runtime.
# For example:

# If flask is not installed, you will get an ImportError saying flask
# is not installed.
# The try keyword is to try running that block of code which may cause an error.
try:
    from flask import Flask
except ImportError:
    print('Flask is not installed! Use pip install flask to install it.')
