(5) IF condition with OR 最后的案例中,我们尝试实现下面的 IF 条件: 当name是Bill或者Emma时,填值 Match 当name既不是Bill也不是Emma时,填值 Mismatch 实现代码如下: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 import pandas as pd names = {'First_name': ['Jon','Bill','Maria','Emma'...
insert :在固定位置插入 例:name_list.insert(3,"python") sort : 排序后特殊字符在前 extend : a+b 或 a.extend(b) copy : 拷贝(深拷贝和浅拷贝) 1)append >>> name_list.append("python") >>> name_list ['shuoming', 'python', 'search', 'python'] 2)index >>> name_list.index("pyth...
但是在WINDOWS / DOS 脚本编程中,IF命令的condition不支持逻辑运算符,所以只好“变相的”来实现。 【解决之道】 一、在cmdA中嵌套IF命令来实现“条件与”,IF命令格式如下: IF [opt] conditionA ( IF [opt] conditionB ( IF [opt] conditionC ( ... ) ) ) 1. 2. 3. 4. 5. 6. 7. 示例 需求:...
{% if condition1 %} do something {% elif condition2 %} do something else {% else %} do something else {% endif %} 在这个示例中,condition1、condition2等都是条件表达式,可以是变量、比较表达式或逻辑表达式。根据条件的结果,Jinja模板会执行相应的代码块。 Jinja模板是Python的一种模板引擎,它可以...
In computer programming, we use the if statement to run a block of code only when a specific condition is met. In this tutorial, we will learn about Python if...else statements with the help of examples.
