In Python, theforloop is used to iterate over a sequence such as alist, string,tuple, other iterable objects such asrange. With the help offorloop, we can iterate over each item present in the sequence and executes the same set of operations for each item. Using aforloops in Python we...
for[first iterating variable]in[outer loop]:# Outer loop[do something]# Optionalfor[second iterating variable]in[nested loop]:# Nested loop[do something] Copy 程序首先遇到外循环,执行第一次迭代。第一次迭代触发内部嵌套循环,然后运行完成。接下来程序返回到外部循环的顶部,完成第二次迭代并再次触发嵌套...

How to Write a For Loop in a Single Line of Python Code? There are two ways of writing a one-liner for loop: Method 1: If the loop body consists of one statement, simply write this statement into the same line:for i in range(10): print(i). Thisprintsthe first 10 numbers to the...
In Python, for-loops use the scope they exist in and leave their defined loop-variable behind. This also applies if we explicitly defined the for-loop variable in the global namespace before. In this case, it will rebind the existing variable. The differences in the output of Python 2.x...

Python does not make use of the decrement operator in the for loop. However, we can emulate the use for decrementing a for loop using other different methods. Let us now discuss how to decrement the for loop in Python. Using the start, stop and step parameters in range() function The ...
