that's not correct. a starts as the string in front of the variable.
for example in "(x+7)^12" it is the empty string "", in "(-x+7)^12" it is the minus sign "-", and in "(0x+7)^12" it is the digit zero "0".
in the second line this string is transformed to the numerical value. so for example "" turns into 1, "-" turn into -1 and "0" turns into 0.
now if a is 0 then the variable isn't relevant and we only have to compute 7^12.

How else would you go about polluting prototypes?
string.toLowerCase()
string.toUpperCase()
string.toJadenCase()

I don't see what you mean. How could someone come up with the same answer without cheating?

But it's still not consistent.

If I understand you correctly you say that curryPartial(curryPartial(double), redundant_parameter) == result is a valid test case
because curryPartial(double, redundant_parameter) == result is a valid test case.

But with the same reasoning curryPartial(double)(redundant_parameter) == result should also be a valid test case. And that's something most current solutions couldn't cope with.

In Python 3 the division of two integers (int / int) results in a float. And floats cannot represent big integers exactly.
If you need the exact results you can use integer division (int // int) and integer modulus (int % int) instead.

Difficult to say in general. I think it depends on your solution.
Usually when you have trouble with the precision of big numbers in python, you accidentally used floats.

You forgot self in the parameter list: def add(self, a, b)

double is a function without parameters, so curryPartial(double) should be result

The description doesn't fully specify the width of the first column.

Just because someone has an opinion doesn't mean it's debatable. 1 + 6 + 7 is 14. There is no room for people expressing their "creativity and come up with different approaches."

This doesn't make sense though. The kata description says that first argument of curryPartial is a function.
