The cool thing about Python loops is that they can be nested i.e. we can use one or more loops inside another loop. This enables us to solve even more complex problems. #1) Nesting for Loops for loops can be nested within themselves. The syntax below shows a 1-level nested for loop....

Python allows you to assign values to multiple variables in one line: ExampleGet your own Python Server x, y, z ="Orange","Banana","Cherry" print(x) print(y) print(z) Try it Yourself » Note:Make sure the number of variables matches the number of values, or else you will get an...
for eachItem in seq: if bool_func(eachItem): filtered_seq.append(eachItem) return filtered_seq 2、map(func,seq1[,seq2...]):将函数func作用于给定序列的每个元素,并用一个列表来提供返回值;如果func为None,func表现为身份函数,返回一个含有每个序列中元素集合的n个元组的列表。 map(function, seque...
By using thenew-stylestring formatting withnumbers(format()method), we can also print the multiple variables. This is similar to method 2 but here we can use the numbers inside the curly braces ({0}), it will help for reordering the values. ...
Now that we know the basics let's go ahead and explore for loops with different object types. For loop with strings We can iterate over the characters of a string like this, forletterin"Python":print(letter) Output: Python In the above example, we iterated over the letters of the word...
范围是不可变的整数序列,通常用于for循环。 Ranges are immutable sequences of integers,and they are commonly used in for loops. 要创建一个范围对象,我们键入“range”,然后输入范围的停止值。 To create a range object, we type "range" and then we put in the stopping value of the range. 现在,我...
