Python【统计数字个数】

输入一系列以空格分隔的1-100的数字，对出现的数字计数。按数字由小到大显示。示例如下：

1 occurs 2 times

2 occurs 2 times

3 occurs 2 times

100 occurs 1 time

import collections
def main():
    # ls = [int(i) for i in input().split()]
    ls = [111,100,11,11,3,2,1,3,2]
    ls.sort()
    b = collections.Counter(ls)

    for c in b:
        if b[c] == 1:
            print(c, "occurs", b[c], "time")
        else:
            print(c, "occurs", b[c], "times")

main()

运行一下，结果：
