使用zip函数:zip函数可以将两个列表中的元素一一对应组合在一起,返回一个可迭代对象。 遍历组合后的变量:在for循环中,我们使用了两个变量num和letter来分别接收组合后的元素,然后打印出来。 类图 PythonDeveloper- name: string- experience: int+PythonDeveloper(name: string, experience: int)+teachForLoopTwoVaria...
方法2:使用enumerate()函数进行迭代 除了使用zip()函数,我们还可以使用enumerate()函数来同时迭代两个变量。enumerate()函数用于将一个可迭代对象组合为一个索引序列,同时返回索引值和对应的元素值。下面是一个示例代码: fruits=['apple','banana','orange']forindex,fruitinenumerate(fruits):print(index,fruit) P...

A deeper discussion on iterables and iterators is beyond the scope of this tutorial. However, to learn more about them, check out the Iterators and Iterables in Python: Run Efficient Iterations tutorial.You can also have a loop with multiple loop variables:Python...
all previous assignments to those variables including those made in the suite of the for-loop: for i in range(10): print(i) i = 5 # this will not affect the for-loop # because i will be overwritten with the next # index in the range Names in the target list are not deleted when...
变量(Variables) 循环(Loop for) 条件(if/elif/else) 过滤(filters) - 特殊内置方法,可以转换变量 测试(tests) - 检查变量是否匹配条件 设置(set) - 变量的一些简化操作 包含(include) - 不同模板组合 Jinja2还允许模板间继承,对我们网络工程师来说,这可能稍微高阶一点了。我们先弄点来“应付”生产,其它的后...
In Python, we can do something called tuple unpacking to get the items inside the tuples printed. For doing so we need to bring two iterable variables in the for loop: for(item1, item2)intup_list:print(item1)print(item2)print('\n') ...
In Python variables,literals,and constants have a "type". Python knows the difference between an interger number and a string For example "+" means "addition" if something is a number and "concatenate" if something is a string >>>ddd=1+4 ...
For Loop You can tackle the for loop in the same way as the while loop. As you probably would have expected, the "for" component in "for loop" refers to something that you do for a certain number of times. If you keep all the above in mind, you can easily define the for loop ...
If the condition of a while loop is always true or the variables within the loop do not update correctly, it may result in an infinite loop. An example of an infinite loop is: while True: # Infinite loop, no break condition Powered By In Python, you can use the break statement to ...
