这就意味着在创建变量时会在内存中开辟一个空间。基于变量的数据类型,解释器会分配指定内存,并决定什么数据可以被存储在内存中。因此,变量可以指定不同的数据类型,这些变量可以存储整数,小数或字符. 一、 变量 1.1 变量赋值 代码语言:javascript 代码运行次数:0 运行 AI代码解释 # Python 中的变量赋值不需要类型声明...

同find 函数类似,index 函数也可以用于检索是否包含指定的字符串,不同之处在于,当指定的字符串不存在时,index 函数会抛出异常,语法格式为:str.index(sub, start, end) str = "abcdefghijklmn" print(str.find("abc")) print(str.find("lmn")) print(str.find("n", 5, 13)) print(str.index("abc")...
