Tuples in Python is a collection of items similar to list with the difference that it is ordered and immutable.Example:tuple = ("python", "includehelp", 43, 54.23) Concatenation of two string tuplesIn this article, we are given two tuples with string elements. We will be creating a ...
First, I want to define“what a tuple is.”A tuple is a set of items in the order. Consider a tuple like a list but with different properties. Because of its immutability properties, you can add, remove, or change the items of the tuple, unlike a list. How a tuple is created: To...

Multiple operations can be performed in Python. You can remove a substring from a string, slice a part of the string, run a for loop over the characters of the string. You can also join two or more strings. When we join two or more string in one string with the help of operators or...
concatenate sequence of strings with a delimited, then use join() function. If some formatting is also required with concatenation, then use format() function or f-string. Note that f-string can be used with Python 3.6 or above versions. You can also learn more aboutpython list concatenation...
You are given a string, S, and a list of words, L, that are all of the same length. Find all starting indices of substring(s) in S that is a concatenation of each word in L exactly once and without any intervening characters. ...
Method 3: Concatenate two arrays Python using numpy.hstack() function The Pythonhstack()numpy function stands for the horizontal stacking. It stacks NumPy arrays in sequence horizontally (i.e., column-wise), increasing the number of columns. If you have two 1D arrays in Python, this function...

No style issues: $ pre-commit run (or $ nox -s pre-commit) (see CONTRIBUTING.md for how to set this up to run automatically when committing locally, in just two lines of code) All tests pass: $ python run-tests.py --all (or $ nox -s tests) The documentation builds: $ python ...
Ah fair! I only knew about Expr.list.concat for the other thing. I stand corrected. I only care about one of those two cases, but as you say it's probably best to have both if it's going to be named analogously. Thinking about it more, I think concat_[list|array] is a bad na...
