Different errors in different programming languages part 1: python

Python errors can be confusing and I want to help you understand them so I am writing this blog post for just that.

Syntax errors:

• Also called parsing errors

• happen when code is parsed/processed to assess for syntax correctness

• you will get this error message for a basic syntax mistake.

correct syntax:

# this will print hello world and there is no error

x = 0

if x == 0:

print("Hello World")

else:

print("x does not equal 0 so this won\'t print")

incorrect syntax:

this is supposed to print hello world but it gives us a syntax error

x = 0

if x == 0:

print("Hello World")

else:

print("This should give us an error")

For the second example: the problem is:

• There is no hashtag for the comments

• there is no indentation

here is another example of a syntax error:

# This is supposed to print "This is true", but it gives us a syntax error

if True != False

print("This is true")

else:

print("This is false"

the issues are:

• There is a missing colon

• there is a missing parenthesis

And there are exceptions

exceptions:

• Errors detected during code execution

There are different exception types in python.

Common built-in Python exceptions include:

• ZeroDivisionError

• TypeError

• IndexError

• NameError

type error:

>>> a = 5 + '4'

index error:

>>> c = [1, 2, 3, 4]

>>> print(c[20])

NameError:

>>> a = b + 15

Zero Division error:

>>> d = 1/0
