Python stringis a sequence of characters. If within any of your programming applications, you need to go over the characters of a string individually, you can use the for loop here. Here’s how that would work out for you. word="anaconda"forletterinword:print(letter) Copy Output: a n ...
Python for 循环Python for循环可以遍历任何序列的项目,如一个列表或者一个字符串。 什么是Python中的for循环? Python中的for循环用于迭代序列(list,tuple,string)或其他可迭代对象。在序列上进行迭代称为遍历。 for循环的语法 for val in sequence: Body of for...
Iterate String using for loop Iterate List using for loop Iterate Dictionary using for loop What is for loop in Python In Python, the for loop is used to iterate over a sequence such as a list, string, tuple, other iterable objects such as range. With the help of for loop, we can ...
print(cuisine) 系统输出: 蒸羊羔 蒸鹿尾 烧花鸭 烧雏鸡 烧子鹅 以上我们利用for循环实现了不同的功能。 下面着重介绍一个在for loop中循环使用else语句的例子。else 中的语句会在循环正常执行完的情况下执行。 三、把else语句放进for loop 例5:我们写一个简单的奇数偶数判别代码: 输入: for i in list(range...
深入理解python中的for循环 Python中的for语句,没你想的那么简单~ for语句实际上解决的是循环问题。在很多的高级语言中都有for循环(for loop)。for语句是编程语言中针对可迭代对象的语句,它的主要作用是允许代码被重复执行。看一段来自维基百科的介绍: Incomputer science, afor-loop(or simplyfor loop) is a...

Python supports three types of for-loops – a range for loop, a for-each expression, and a for-loop with enumeration. Below are examples of each of these loops. A range for-loop goes from a low numerical value to a high numerical value, like: for i in range(0,3): print i It p...
print(i) Yields below output. 3. Using range() Get For Loop in Backwards Pythonrange()function is used to generate a sequence of numbers within a given range. You can use the range() function with a negative step value to implement the loop iterations from in backside rather than the fr...
python fruits = ['apple', 'banana', 'cherry']for fruit in fruits:print(fruit)这将打印：apple banana cherry 在for循环中，我们还可以使用else语句来执行一些代码，当循环正常结束时，而不是因为break语句或异常而结束时。例如：python for num in range(5):print(num)else:print('Loop has ended ...
The code below returns a sequence of each string in a sentence: a ="How to use a for loop in Python" foriina: print(i) We can also count the number of strings (including spaces) in the variableausing aforloop: a = ["How to use a for loop in Python"] ...
