标签：python float strong 返回结果 add efi 需要 访问 location
#Say something NOT IMPORTANTPython不需要用int, float, double来define变量
短路计算。
所以，Python解释器在做布尔运算时，只要能提前确定计算结果，它就不会往后算了，直接返回结果。
够懒！！
python classmates = [‘Michael‘, ‘Bob‘, ‘Tracy‘]
与数组相同，例如classmate[0] = Michael，此外，List还可以倒序访问，例如classmate[-1] = Tracy
#Say something NOT IMPORTANT
classmate.append("new_classmate") #Add in the END
classmate.insert(1,"new_classmate") #Add in the 2nd location#Say something NOT IMPORTANT
classmate.opp() #Delete the FINAL
classmate.insert(1) #Delete the 2nd#Say something NOT IMPORTANT
classmate[0] = 'You'
classmate[-1] = 'Me'tuple一旦创建就不能修改
Like List
classmates = ('Michael', 'Bob', 'Tracy')
className = ('Metoo',) #Create single elementt = ('a', 'b', ['A', 'B'])
L = t[2]
L[0] = 'hha'
L[1] = 'lla'标签：python float strong 返回结果 add efi 需要 访问 location
