Answer to Question #179562 in Python for FORTUNE AIDOO

Question

Include example Python code and output with your answers.

• If you are trying to print a string, what happens if you leave out one of the quotation marks or both and why?
• You can use a minus sign to make a negative number like -2. What happens for each of the following and why?

>>> 2++2

>>> 2--2

>>> 2+-2

>>> 2-+2

• In math notation, leading zeros are OK, as in 02. What happens if you try this in Python and why?
• What happens if you have two values with no operator and a space in between them and why?

Answer 1

print(2++2)  # 2 + (+2) = 4
print(2--2) # 2 - (-2) = 4
print(2+-2) # 2 + (-2) = 0
print(2-+2) # 2 - (+2) = 0

if you have two values without an operator and a space between them, then python will throw the SyntaxError: invalid syntax error

if you omit the quotation mark, you will get the SyntaxError: EOL while scanning string literal error, because it is not possible to determine the beginning or end of the string

python does not allow leading zeros, there will be a SyntaxError error: leading zeros in decimal integer literals are not allowed; use the 0o prefix for octal integers
