Statement- 执行某个动作的单行代码。 Conditional Statement- 根据条件执行不同代码块的语句,如if语句。 Loop- 重复执行代码块的控制结构,如for和while循环。 Comment- 代码中不被执行的解释性文本。 Syntax- 规定Python代码应如何编写的规则。 Indentation- 用于格式化代码和定义代码块的空格或制表符。 Assignment- 使...
# Define the data to be evaluated data = [3, 5, 2, 8, 4]# Use a for loop to evaluate each element in the data for num in data:# Use the ternary operator to determine if the number is even or odd result = 'even' if num % 2 == 0 else 'odd'# Optionally, print the result...
Expression：在代码中评估的数学或逻辑运算。Operator：在代码中执行特定操作的符号。Variable：在程序中存储...
Python 里面的「for 循环」很像读英文。通用形式的 for loop 如下: for a in A do something with a 1. 2. 其中for 和 in 是关键词,A 是个可迭代数据 (list, tuple, dic, set),a 是 A 里面的每个元素 enumerate 函数 enumerate(A) 不仅可以 A 中的元素,还顺便给该元素一个索引值 (默认从 0 开...
Infinite loops can be very useful. Just remember that you must ensure the loop gets broken out of at some point, so it doesn’t truly become infinite. NestedwhileLoops In general, Python control structures can be nested within one another. For example,if/elif/elseconditional statements can be...
A common use of the conditional expression is to select variable assignment. For example, suppose you want to find the larger of two numbers. Of course, there is a built-in function, max(), that does just this (and more) that you could use. But suppose you want to write your own co...

博文结构Python的if语句Python的for循环了解Python安装及操作一.Python条件判断条件语句是指根据条件表达式的不同计算结果,使程序流转到不同的代码块。Python语句是if语句和ifelse语句。if条件语句if语句用于判断某个条件是否成立,如果成立,则执行语句内的程序,否则跳过if语句执行后面的内容,语法格式如下:if(条件):语句块...
Similar to “while” we can also use “break” and “continue” statements in “for” loop as well. Now we are done with the conditional statements and move forward with other structures. Modules Sometimes there is a need to reuse the code or manage it depending upon our requirement, this...
