a=(a)
((a))
((a))
b=(b)
((b))
((b))

老师，这里面a和=、b和=之间需要空格吗，有什么要求？

This probably means that Tcl wasn't installed properly.

进程已结束，退出代码为 1

老师，没有社区版本

a = "我是{0}，我的存款有{1:.2f}".format("高淇,3883.2323)

老师，这一直报错 帮忙看看。

提示 KeyError: '1：'  这个报错

help()

怎么运行不出现窗口

当输入错误时，怎么及时修改for循环次数，

time

a = ():
    = time.time()
    a
    i ():
        a += = time.time()
(.format((end-start)))
():
    = time.time()
    c = i ():
        c += = time.time()
(.format((end-start)))

aaa()
bbb()

老师哪里错了，懵了

为什么没有c

def f3(*a,**b,c):
    print(a,b,c)

f3(10,20,30,name="gaoqi",age=19,c=20)

这个的最后一个大小写互换为什么只将大写换位了小写呀？

有没有可以推荐写代码的网站，挣点外快

score=int(input('请输入一个在0-100之间的数字'))
degree='ABCDE'
num=0
if score>100 or score<0:
   score=int(input('输入错误！请重新输入一个在0-100之间的数字'))
else:
   num=score//10
   if num<6:num=5
print('分数是{0}，等级是{1}'.format(score,degree[9-num]))

这个代码输入是100的时候，系统判断的等级是E

请问，is not 和 not is 有什么不一样？

我在运行      

 a="abcdef"

 b="abcdef"

print(a is not b) 时，能跑起来。但是

运行print(a not is b)时会报错？
