In Python, many statements can cause errors, but I would like to know what are the simplest statements that can cause an Error except for NameError and SyntaxError and their subclasses such as IdentationError

Using the interactive Python shell, I have tried using single characters in statements but they are all NameErrors or SyntaxErrors, and I tried two characters, it is also the same, so I wonder if there are any possibilities to cause other types of errors by using 3 or fewer characters in Python. if this is impossible, then why so?

CodePudding user response：

I think the shortest one would be a three-character ZeroDivisionError. Like this:

1/0

Almost everything that isn't a NameError or SyntaxError is going to need some kind of operator, which will bump you up to three characters.

CodePudding user response：

bitwise negation of a float raises TypeError in 3 characters

>>> ~.0
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary ~: 'float'

CodePudding user response：

Your question is unclear if you are looking for the absolute shortest code to cause an error, or if you are looking for several short examples that cause a variety of different errors.

For the later, add these two to your list:

x, = 5 # TypeError

and

x, y = 5, # ValueError

and

x, = [] # ValueError

Not quite as short as Michael M's answer, but still short.

only available in the interpreter

nothing and ^C

>>> 
KeyboardInterrupt

CodePudding user response：

You can cause a TypeError by trying to negate a tuple, for example:

>>> -()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary -: 'tuple'
