for loop in Python Syntax of for loop for i in range/sequencee: statement 1 statement 2 statement n In the syntax, i is the iterating variable, and the range specifies how many times the loop should run. For example, if a list contains 10 numbers then for loop will execute 10 times...
python for-loop if-statement list = ["Donald, Trump", "Joe, Biden", "Barack, Obama"] while True: name = input("Name: ") for short in list: if name in short[0]: print("It Work") else: print("It Don't Work") 它应该打印“It Work”,因为我提供的答案在列表中,但是它不读取if...

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语句其实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 acontrol flowstatementfor specifyingiterati...

Anytime you have need to repeat a block of code a fixed amount of times. If you do not know the number of times it must be repeated, use a “while loop” statement instead. For loop Python Syntax The basic syntax of the for loop in Python looks something similar to the one mentioned...
如果是,将对应的键值设置为True;否则,设置为False。 状态图 为了更清晰地展示上述示例中的流程,我们可以使用状态图来表示。 StartForLoopIfStatementTrueResultFalseResultEnd 在这个状态图中,我们有以下几个状态: Start:开始状态,表示代码的起点。 ForLoop:表示for循环中的操作。 IfStatement:表示判断语句...
