a = (1,2,3) 支持list的很多操作,唯独不能对一个tuple自身进行修改 所以dict 因为要求 key 值不可变,当想对插入一个 (list,int)键值对时,必须将 list 转为 tuple str(字符串) 和C++ 中字符串类似,但是无法修改其中字符,因此经常用如下方法转换为一个list再进行操作。
虽然in 和not in 操作在通常情况下,被用于简单的成员检测 python >>> "ya" in "pitaya" True >>> "K" in "Karene" True >>> "a" in ["b",5,[2,"4"]] False 小于0 的n 值会被当作 0 来处理 (生成一个与 s 同类型的空序列)。 python >>> list1 = [] >>> list1 [] >>> list...
To create a list and initialize with values, you can enclose the values in square brackets, separated by commas. Create and initialize Python list my_list = [1, 3, 2, 4] print(my_list) # [1, 3, 2, 4] Unlike some programming languages, lists in Python can be made up of various...
