Integer to Roman 问题简介:将输入的int类型数字转化为罗马数字 问题详解:罗马数字由七个不同的符号表示:I,V,X,L,C,D和M 符号-数值 I - 1 V - 5 X -10 L - 50 C - 100 D - 500 M - 1000 例如,2用罗马数字写成II,只有两个I加在一起,十二写为XII,解释为X + II, 二十七写成XXVII,即XX + V + II, 罗马数字通常从左到右从最大到最小,但是,四个数字不是IIII,相反,第四个写为IV,因为一个在五个之前…

本篇阅读的代码实现了将输入的数字转化成一个列表,输入数字中的每一位按照从左到右的顺序成为列表中的一项. 本篇阅读的代码片段来自于30-seconds-of-python. digitize def digitize(n): return list(map(int, str(n))) # EXAMPLES digitize(123) # [1, 2, 3] 该函数的主体逻辑是先将输入的数字转化成字符串,再使用map函数将字符串按次序转花成int类型,最后转化成list. 为什么输入的数字经过这种转…
