Write a Python program to create a list by concatenating two lists element-wise. Write a Python program to generate a list by concatenating words from a list with numbers from a range. Write a Python program to create a list of strings by appending a given suffix to each element. Write a...
Write a Python program to generate all possible combinations of the elements of a given list using itertools.combinations and then sort them by length. Write a Python program to create an iterator that yields all non-empty combinations of a list and then filter out those that do not meet a ...

You can even use combinations of a Boolean object and a regular one. In these situations, the result depends on the truth value of the operands. Note: Boolean expressions that combine two Boolean operands are a special case of a more general rule that allows you to use the logical ...
The chars argument is a string specifying the set of characters to be removed. If omitted or None, the chars argument defaults to removing whitespace. The chars argument is not a prefix or suffix; rather, all combinations of its values are stripped str.replace(old, new[, count]) https:...
https://oj.leetcode.com/problems/combinations/ Given two integers n and k, return all possible combinations of k numbers out of 1 ... n. For example, If n = 4 and k = 2, a solution is: [ [2,4], [3,4], [2,3],
That’s also why the interpreter prints an empty set as set() instead of {}. 5. What if you want to check for combinations of set values? Suppose that you want to find any drink that has orange juice or vermouth? Let’s use the set intersection operator, which is an ampersand (&)...

Python allows you to do this with something called verbose regular expressions. A verbose regular expression is different from a compact regular expression in two ways: • Whitespace is ignored. Spaces, tabs, and carriage returns are not matched as spaces, tabs, and carriage returns. They’re...
