Python语法入门_:输入用户姓名,输出用户名字的首字母后面加上最多7位作为用户名。

一：下面我就以几个小程序入门：

PS：先举几个例子复习一下有关类，继承的知识：
（1）类

class Employee:
    empCount=0

    def __init__(self,name,salary):
        self.name=name
        self.salary=salary
        Employee.empCount+=1

    def displayCount(self):
        print "Total Employed %d" %Employee.empCount

    def displayEmployee(self):
        print "name:", self.name, ",salary:", self.salary

emp1=Employee("wang",10000)
emp2=Employee("zhang",8000)
emp1.displayEmployee()
emp2.displayEmployee()
print "Total Employee %d" %Employee.empCount

（2）继承

class Employee:
    empCount=0
    def __init__(self,name,salary):
        self.name=name
        self.salary=salary
        Employee.empCount+=1

    def displayCount(self):
        print "Total Employed %d" %Employee.empCount

    def show(self):
        print "parentWay"
class Employee1(Employee):
    def __init__(self):
        print "childMethod"
    def displayCount(self):
        print "childWay"
emp1=Employee("wang",10000)
emp2=Employee("zhang",8000)

emp3=Employee1()
emp3.displayCount()
emp3.show()

1.问题：在温度刻画的不同体系中，摄氏度以1标准大气压下水的结冰点为0度，沸点为100度。华氏度以1标准大气压下水的结冰点为32度，沸点为212度。如何利用程序辅助进行摄氏度和华氏度之间的转换。
分析：根据华氏和摄氏温度定义，其单位刻度对应温度关系为(212-32)/(100-0)=1.8，转换公式如下：
C = ( F – 32 ) / 1.8
F = C * 1.8 + 32
