Python基础:循环语句

Python常用的循环函数是 while 和 for 先说明while循环的格式 while 循环条件: 代码段如: i = 10 while i > 0: i-=1 print(i) 将会依次打印出9 - 0 for循环也是类似: for 临时变量 in 目标对象: 代码段如: for i in [0,1,2,3]: print(i) 将会打印出数据集内全部数据当然也可以依次遍历字符串如: for i in "Python Go": print(i) 将会依次打印单个字符结果死循环用法: while True: 代码段另外可以用: while(循环条件) 以及 for(i in "Python")这种用括号包含条件的方法

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

Java基础:方法定义

Java方法定义格式为: public static void 方法名称(参数){...} 例如: public static void test_fun(){ System.out.println("我的第一个方法"); } 调用方法就是直接 test_fun(); 使用void创建方法是不能使用return来返回结果的想要返回结果需要使用其他类型例如: public static int 方法名称(参数){... return int} 这样的写法就可以返回一个int参数，其他类型也是一样的例子 -------下面讲讲其他语言的方法定义方式------- 首先就说说PHP的方法定义: function 方法名(参数){...} PHP定义方法时不需要定义方法的数据类型，可直接使用return返回各个类型的数据另外就是C语言，定义方式: void 方法名(参数){...} C语言也是和Java类似，也是需要再定义时决定数据类型才可以进行返回相应的数据类型，例如int 方法名(参数){...}这样就可以返回一个int类型的

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

ASCII 打印字符

ASCII 打印字符 (字符编码: 32-127) 32～126(共95个)是字符：32是空格，其中48～57为0到9十个阿拉伯数字，65～90为26个大写英文字母，97～122号为26个小写英文字母，其余为一些标点符号、运算符号等。第127个字符表示的是键盘上的删除命令。 32-127ASCII码对应值在下方

Java StringBuilder基本用法

//StringBuilder类型示例 public class demo3 { public static void main(String[] args) { //StringBuilder 定义的数据是可改变的 //String 定义的数据是不可改变的，每次覆盖都会产生新的变量 StringBuilder strb1 = new StringBuilder("1123"); //必须使用new方法进行赋值，数据存储在堆中 strb1.append("abc"); //使用append在str1后面添加新的数据，类似一个伪数组同样可以通过charAt的方式访问索引 System.out.println(strb1.charAt(5)); //返回5索引的字符 System.out.println(strb1); StringBuilder strb2 = new StringBuilder("ceshi123"); strb2.reverse(); //容器内的数据进行翻转 String str = strb2.toString(); //StringBuilder类型转为String类型，返回String类型数据 System.out.println(strb2); System.out.println(str); } }

Python基础:变量与数据类型

Python定义变量的方法为: name = "chumo" age = 19 也可以同时定义: name,age = "chumo",19 两种方法定义都是一样的结果定义变量时不需要像c语言以及java那样先声明数据类型再写入变量内容。 Python常见的数据类型有: Number（数字） String（字符串） List（列表） Tuple（元组） Set（集合） Dictionary（字典）
