while expression: (tab)statement(s)其中,expression是条件表达式,statement(s)是要执行的代码块。基本用法 while循环的基本用法很简单,只要expression为真,就会一直执行statement(s)。下面是一个简单的例子:count = 0while count < 5:(tab)print(count)(tab)count += 1 这个例子会输出0到4这五个数字,因...
\tPrints tab space \bPrints backspace \fPrints form feed \oooPrints octal value \xhhPrints hexadecimal value Example # Example of escape characters# \'print("Hello 'Alex!'")# \\print("Hello\\Alvin!")# \nprint("Hello\nBobby!")# \rprint("Hello\rCristina!")# \tprint("Hello\tDen!
print(x == y) #True print(x == z) #True print(x is y) #True print(x is z) #False (9)选择 1、Python代码的缩进规则。具有相同缩进的代码被视为代码块 2、缩进请严格按照Python的习惯写法:4个空格,不要使用Tab,更不要混合Tab和空格 3、格...
dic={} 字典是python 中唯一的映射类型(哈希表) 字典对象是可变的,但是字典的键必须使用不可变对象,一个字典中可以使用不同类型的键值。 字典的方法 :dic. +tab (1) dic.clear 删除字典内所有元素 (2)get() 返回指定键的值,如果值不在字典中返回default值。 语法:dict.get(key,default=None) dic.iter...

indented statement(s) # 循环体语句 while循环中这个条件通常是一个判断真假的布尔表达式,或是一个真假测试(True/False)。 while循环中,只要条件为真,while循环就会持续重复循环中的语句,判断真假条件往往涉及到比较值。 比较操作符: x = 1 while x < 10: ...
