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:
# Some Code....
except:
# optional block
# Handling of exception (if required)
else:
# execute if no exception
finally:
# Some code .....(always executed)
