Python Learning Note (vi) operator

Arithmetic operators in Python:

+-*/% *//

Attention:

/: For real division, which corresponds to the division in mathematics, usually returns a floating-point number

: Take the divisible method, namely the pick-up

%: modulo, which takes the remainder

* *: Power operation, one thing to note here is that the power operator precedence is higher than the single-mesh operator on its left, and has a lower precedence than the single-operator on its right.

Priority level:

• Power Operation * *
• PLUS sign +-
• Arithmetic operator *///
• + -
• Compare operators < <= > >= = = = =
• Logical operator not > and > or

From top to bottom, the priority gradually decreases.
