Why am i Getting this Error??? Enter a number: Traceback (most recent call last): File "..\Playground\", line 1, in <module>

Answer 1

Because you have an error in the code submitted to be executed...

... but without the complete error message and/or the code, nobody could say more accuratly why ^^

Answer 2

where's Your code?
1st line has got a broken syntax .
1st line is autocompleted here - perhaps You have mistakely clicked some button or even either...
Crreate a new code and compare 1st lines.
Maybe You include package being unsupported here?
