我开始学习函数了,我写了这个简单的脚本:
def add(a,b): return a + bprint "The first number you want to add?"a = raw_input("First no: ")print "What's the second number you want to add?"b = raw_input("Second no: ")result = add(a,b)print "The result is: %r." % result
脚本运行正常,但结果不是总和.即:如果我为’a’输入5,为’b’输入6,结果将不是’11’,而是56.如下:
The first number you want to add?First no: 5What's the second number you want to add?Second no: 6The result is: '56'.
任何帮助,将不胜感激.
解决方法 raw_input返回string,需要将其转换为intdef add(a,b): return a + bprint "The first number you want to add?"a = int(raw_input("First no: "))print "What's the second number you want to add?"b = int(raw_input("Second no: "))result = add(a,b)print "The result is: %r." % result
输出:
The first number you want to add?First no: 5What's the second number you want to add?Second no: 6The result is: 11.总结
