Python基础:常用格式化输出方式

首先常用的格式化输出有: 使用 % 占位符输出，常用的占用符可以在贴图中查看用法: name = "Chumo" font = "My Name Is %s" print(font % (name)) 这里用的是%s字符串占位符，string的首字符s 使用%d输出整数: age = 19 font = "今年%d岁" print(font % (age)) 多个参数用法: name = "Chumo" age = 19 font = "我是%s今年%d岁" print(font % (name,age)) 上面就是基本的占位符输出用法接下来就是使用 format 格式化用法: age = 19 font = "今年{}岁" print(font.format(age)) 扩展：使用位置和关键字参数 print('我的名字是 {0}, 我的年龄是 {1}'.format(name,age)) print('我的名字是 {name}, 我的年龄是 {age}'.format(name="Chumo",age=18)) 上面是基本的format格式化输出方法然后是 f-string 格式化输出方法用法: name = 'chumo' age = 18 print(f'我的名字是 {name}, 我的年龄是 {age}') 要注意print函数中的 f 字符，在输出内容前加一个f字符，就可以直接将变量在字符串中调用{name} 上面是三种常用的格式化输出变量方式接下来就是输出字符保留N位小数点方式: 首先说的是 % 占位符输出保留小数点的写法，首先保留小数点肯定是需要一个浮点型的数据，这边浮点数据用的是%f也就是float的首字符f来表示: name = 'chumo' age = 18.43 print(f'我的名字是 {name}, 我的年龄是 %f' % (age)) 输出结果为:我的名字是 chumo, 我的年龄是 18.430000 默认是保留小数点后面6位数据，怎么让他只保留两位呢? 我们可以用 %.2f 的方式保留两位小数: name = 'chumo' age = 18.43 print(f'我的名字是 {name}, 我的年龄是 %.2f' % (age)) 最后输出的结果为:我的名字是 chumo, 我的年龄是 18.43 想要保留更多小数可以在%.2f中修改数字大小来实现:%.3f就是保留三位接下来就是format函数保留小数点的方法: age = 18.43 print('我的年龄是{:.2f}'.format(age)) 用的是 {:.2f} 保留两位小数的写法前面的 : 符号是什么意思呢？其实看下面这个例子就会知道: name = 'chumo' age = float(18.43) print('我的名字是 {name}, 我的年龄是{age:.1f}'.format(name=name,age=age)) 可以看到用的是{age:.1f}的方式输出保留小数点后一位里面的 : 就是将 age 与后面的小数点长度区分开来最后是第三种方法f-string格式化(python3.6以后的版本中可以使用) name = 'chumo' age = 18.43 age = round(age,1) print(f'名称{name}年龄{age}') 这种方法我前面介绍过了，是不需要区分数据类型就可以直接进行输出的需要用到 round 函数处理浮点数保留的位数

C语言基础: 逻辑运算符

基本的逻辑比较运算符在前面笔记说过了链接:http://notei.cn/note_see/64 这里主要是讲与运算或运算非运算学过一点电子逻辑门都应该有点概念的与运算在C语言中用的符号是 "&&" 实际用法就是: if(10>=5 && 6<=5)，顾名思义与逻辑就是要让两个逻辑同时为真最后才能返回真条件，反之就是假条件。最后会返回的结果为0，为什么10>=5明明是真条件为什么会等于0呢？是因为6<=5是假条件导致整个运算结果也为假条件。也可以多个条件一起进行运算if(1==1&&2==2&&3==3)多个条件一起运算也是可以的，如果三个条件都为真，那么最后会返回一个真条件，反之假条件。或逻辑运算方式为只要有一个条件为真，那么最后就会返回真条件。反之全部为假条件，最后也只能返回假条件。符号为 "||" 用法为:if(1==1||2==3)。非逻辑就是在条件的前面加一个 "!" 也就是小写的感叹号，让最后的逻辑取反。如果逻辑为真后加一个"!"条件将会变成假条件，反之为真。

C语言数组定义解释

一维数组定义方式为: int a[] = {0,1,2,3,4,5,...}; 或 int a[3] = {0,1,2}; 第一种定义方式没有指定元素数量，第二种固定三个元素进行传参，如果int a[4] = {0,1,2};，那么第四个元素默认是0 二维数组定义方式为: int a[][] = { {1,2,3}, {4,5,6}, {7,8,9} }; int a[][] 代表的是要定义一个二维数组，=后面的值为二维数组的内容 a[0]输出结果为数组{1,2,3}，a[1]输出结果为数组{4,5,6}，那么a[0][1]输出为1，a[1][1]输出为4，a[1][1]输出为5 ----------以上是我觉得的---------- 和我学的PHP JS等语言不太一样的数组处理方式，深层逻辑我也不懂。就以我学的PHP来说，PHP的数组定义: $a = []; 就是定义一个空数组 $a[] = 123; 就是将变量a数组的首个元素指定为123 $a[] = 123;$a[] = 456;将0键值的数据指定为123，将1键值的数据指定为456 --上面是PHP定义一维数组的基本方法-- PHP二维数组的定义方式和C语言也有一样的地方: $a = [ [1,2,3], [4,5,6], [7,8,9] ]; 定义和C语言一样的二维数组当然也有不一样的地方: $a[0] = [0,1,2]; $a[1] = [3,4,5]; $a[2] = [6,7,8]; 这样定义出来也是一样的二维数组 ----------下面为我个人理解---------- 首先C语言的int a[][] = {{},{}}格式和PHP的$a = [[],[],[]]类似 int a[][] 代表的是告诉系统要定义一个二维数组，=后面的值为二维数组的内容而PHP可以直接指定一维数组的键值等于另外一个数组，从而达到二维数组的定义只是自己做个笔记理解一下两个语言的数组定义方式以及不同，C我也是刚学不久不是很理解，就先写个笔记记录一下了

Uni-App学习:Vue计算属性computed

如果我们想通过一个成绩来得到等级: <span>{{ author.chengji >= 85 ? '优' : '良' }}</span> 可以在标签内渲染一个计算结果达到目的，不过这样会导致运算代码和其他标签内容混淆看起来很臃肿，我们可以通过Vue的计算属性computed来达到分开计算的方法: computed: { chengji:function() { return this.chengji >= 85 ? '优' : '良'; } } ><span>{{ chengji }}</span> 计算属性值会基于其响应式依赖被缓存，如果计算的参数没有发生改变，那么就会直接调用缓存中的结果，而不用再次调用函数获取结果如果使用methods方法来计算的话，每当数据改变时页面会重新渲染，全部函数将全被执行
