2 C++ includes arand()functiono to yield an integer range from 0 to implementation-dependent value. If you want smaller range, use rand() modulus the range you desired. Actually, the rand() is reallypseudorandombecause rand() works by applying an algorithm to an initial seed value to get...
for index in range(len(seasons)): #range是生成一组序列的意思 print index print seasons[index] 1. 2. 3. 4. 循环使用 else 语句: 在python 中,for … else 表示这样的意思,for 中的语句和普通的没有区别,else 中的语句会在循环正常执行完的情况下执行,while … else 也是一样。
