Example: Loop Through a String If we iterate through a string, we get individual characters of the string one by one. language ='Python'# iterate over each character in languageforxinlanguage:print(x) Run Code Output P y t h o n ...
Definite Iteration: When we know how many times we wanted to run a loop, then we use count-controlled loops such as for loops. It is also known as definite iteration. For example, Calculate the percentage of 50 students. here we know we need to iterate a loop 50 times (1 iteration fo...
When you use for loops to transform data and build new collections, it may be possible to replace the loop with a comprehension. For example, consider the loop below: Python >>> cubes = [] >>> for number in range(10): ... cubes.append(number**3) ... >>> cubes [0, 1, 8...

在编辑器中点击运行按钮,或者在命令行中使用python loop_example.py命令来运行代码。 当你运行代码后,你应该能够看到类似下面的输出: 这是第 1 次循环 这是第 2 次循环 这是第 3 次循环 ... 这是第 20 次循环 1. 2. 3. 4. 5. 如果你看到了这些输出,并且总共有20行,那么恭喜你,你已经成功地实现了...
for i in myList: print (i) 1. 2. As we can see we are using a variablei, which represents every single element stored in the list, one by one. Our loop will run as many times, as there are elements in the lists. For example, inmyListthere are 6 elements, thus the above loop...
