# Review:Built_in Function I need your guys' help

#1

I know the code is wrong,but if i don't want to type something like 'if type(x)==int or type(x)==float'.Because the code is a little long.What should i do to save some time.Thank you guys so much.

``````def distance_from_zero(x):
if type(x)== int or float:
return abs(x)
else:
return 'Nope'``````

#2

i don't know but your code works for me

#3

If you try a string,the answer will not be 'False'

#4

yeah , you are right , so this what i found

``````def distance_from_zero(x):
if type(x) is (float or int):
return abs(x)

else:
return 'Nope'

print distance_from_zero(-4)``````

#5

Yeah,you're right.So it seems that we should see the code after 'is' as a whole.

#6

I try your code again.I don't know why it doesn't work this time.

#7

can reply to me the output error ??

#8

yeah me to , i try it now didn't work i don't know why ??

#9

I think the problem is the priority of '==' and 'or'.I try to use some brackets like the following:

``````def distance_from_zero(x):
if type(x) == (int or float):
return abs(x)
else:
return 'Nope'``````

but it still doesn't work.

#10

This needs to be two complete expressions with nothing implicit; i.e., `(int or float)`...

``if type(x) == int or type(x) == float:``

#11

I know that.I just want to explore a laconic way to type the code.Have any great idea?

#12

In terms of expressions, we don't have ways to reduce them. They are the operands; However, Python has tuples that can be explored to this effect. Take a gander down that avenue and report back what you find. It will be interesting, for sure.

#13

I've studied tuple yet.But i believe when i encounter the knowledge you say,the words you say will inspire me.

#14

if you find anything let me know ( tag me )

#15

def distance_from_zero(x):

``````if type(x) == int or type(x)==float:
return abs(x)

else:
return 'Nope'``````

print distance_from_zero(10)

mucho mejor!!

#16

We've already known how to solve this problem but then we tried to make the code easier.Have any great idea?

#17

``````def distance_from_zero(x):
if type(x) in [float,int]:
return abs(x)
else:
return 'Nope'``````

#18

Or,

``````def distance_from_zero(x):
return abs(x) if type(x) in [float,int] else 'Nope'``````

#19

is the best i can do!
