What is NaN in list Python?
Nan implies “not a number” in python language. It is usually a float-type value that does not exist in data. Due to this reason, data users must remove “nan” values. There are numerous approaches available to remove “nan” values from a list data structure.
Why am I getting NaN in Python?
Nan means “Not a number”, this is because inside your cube function, you’re not calling the square function, but getting it’s contents. Change return x * square; with return x * square(x); and it should work.
What is NaN data?
NaN stands for Not A Number and is one of the common ways to represent the missing value in the data. It is a special floating-point value and cannot be converted to any other type than float. NaN value is one of the major problems in Data Analysis.
Is Python string NaN?
isnan() is a built-in Python method that checks whether a value is NaN (Not a Number) or not. The isnan() method returns True if the specified value is a NaN. Otherwise, it returns False.

Why is NaN a number?
