WebWe have created a function called binary_search () function which takes two arguments - a list to sorted and a number to be searched. We have declared two variables to store the lowest and highest values in the list. The low is assigned initial value to 0, high to len (list1) - 1 and mid as 0. WebJul 11, 2024 · But seriously, Python numbers are complicated. If you really a regex that will match ALL valid forms of Python numbers, it will be a complex regex. Integers include decimal, binary, octal, and hexadecimal forms. Floating point numbers can be in exponent form. As of version 3.6 all kinds of numbers can have '_' in them, but it can't be first or ...
