Answer to Question #256339 in Python for Raymond Ekwubiri

Question

Describe how catching exceptions can help with file errors. Write three Python examples that actually generate file errors on your computer and catch the errors with try: except: blocks. Include the code and output for each example in your post. Describe how you might deal with each error if you were writing a large production program. These descriptions should be general ideas in English, not actual Python code.

Answer 1

Catching exceptions can help with errors in that whenever a runtime error occurs, it creates an exception object. This program stops running and python prints out the traceback, which ends with a message describing the exception that occurred.

#example one
try:
    N = 42
    N = N+ ' 4 '
except TypeError:
     print('Wrong type')


#example two
try:
    m = []
    print(m[1])
except IndexError:
    print("Index error")


#Example three dividision by zero
try:
    y=int(input("Enter an interger: "))
    x = y/0
    print(x)
except ZeroDivisionError:
    print(Zero)
