for it1, e1 in enumerate(t1): for it2, e2 in enumerate(t2): if e1==e2: t3.append((it1,it2,e1)) # t3=[(0, 0, 1), (2, 1, 'Hello'), (3, 2, (1, 2)), (4, 3, 999)] 这可以简化为单一理解: [(it1,it2,e1) for it1, e1 in enumerate(
方法1:使用zip()函数进行迭代 在Python中,zip()函数可以将两个或多个可迭代对象打包成一个元组序列。我们可以使用这个特性来实现使用两个变量的“for循环”。下面是一个示例代码: fruits=['apple','banana','orange']prices=[0.5,0.3,0.4]forfruit,priceinzip(fruits,prices):print(fruit,price) Python Copy ...

In Python, loops can be used to solve awesome and complex problems. You will likely encounter problems that would require you to repeat an action until a condition is met(while loop works best here) or a problem that requires you to perform an action on a bunch of items(for loop works ...
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: In computer science, a for-loop (or simply for loop) is a control flow statement...

“从零开始,一点一滴地分享所有我学到的Python知识。” 一、综述 在一般情况下,程序是按顺序依次执行的。但,循环(loop)语句允许我们多次执行一个语句或一组语句。 Python中的循环语句可分为以下几种:for循环,while循环和嵌套循环。其中,嵌套循环指,在一个循环里嵌套了另一个循环的循环体。
With theforloop we can execute a set of statements, once for each item in a list, tuple, set etc. ExampleGet your own Python Server Print each fruit in a fruit list: fruits = ["apple","banana","cherry"] forxinfruits: print(x) ...
for Loop with Python range() In Python, the range() function returns a sequence of numbers. For example, # generate numbers from 0 to 3 values = range(0, 4) Here, range(0, 4) returns a sequence of 0, 1, 2 ,and 3. Since the range() function returns a sequence of numbers, we...
