Python itertools.chain() method to concatenate lists Python itertools modules’ itertools.chain() function can also be used to concatenate lists in Python. Theitertools.chain()function accepts different iterables such as lists, string, tuples, etc as parameters and gives a sequence of them as ou...
Let's see a little more about howstrings work strings can be addedtogether 字符串也可以相加(联接起来) yousee how adding those two stringstogether just push them together Ididn't include a space so the computerdidn't put one there either 上面的例子中字符串拼接,因为没有输入空格,所以两个文本...
.format(z)) # Add two lists together a = [1, 2, 3, 4] b = ["first", "second", "third", "fourth"] c = a + b print("Output #3: {0}, {1}, {2}".format(a, b, c)) Tip The lines that are preceded by a # are comments, which can be used to annotate the code ...
In the second part of the tutorial, you saw more advanced decorators and learned how to: Decorate classes Nest decorators Add arguments to decorators Keep state within decorators Use classes as decorators You saw that, to define a decorator, you typically define a function returning a wrapper fun...
()function to add two lists element-wise. It allows lists of unequal lengths. It finds a smaller list between the two and then iterates over the elements of the shorter list using for loop.append()function returns the sum of two elements. The sum is appended to the resultant list. This...
Python code to sort two lists according to one list Combining them together, we canorderthe 2 lists together by new_x, new_y = zip(*sorted(zip(x, y))) For the above example, thenew_xandnew_ywill be: >>> new_x, new_y = zip(*sorted(zip(x, y)))>>> new_x (1,2,3,...
You can add as many packages as you want to the pip install command. In cases like this, a requirements.txt file can come in handy. Later in this tutorial, you’ll learn how to use a requirements.txt file to install many packages at once....

In this article, we learned to join two or more sets by using several built-in functions such asupdate(),union(),reduce()and operators like|,*etc and we used some custom codes as well. We learned about the difference between lists and sets and how we can convert a set to a list. ...
