Function pointers, Closures, and Lambda
...why, in C#, you can do:
int lessThan = 100;
Func<int, bool> lessThanTest = delegate(int i) {
return i < lessThan;

Can you list the keyword arguments a function receives?
... set() # All accepted

And so a full test if it is callable is :
def isCallableWithArgs(func, argdict):

...25 F01 300 1:13:37:1,13
If in column are NOT NaN values, the fastest solution is use list comprehension with DataFrame constructor:
df = pd.DataFrame(['a b c']*100000, columns=['col'])
In [141]: %timeit (pd.DataFrame(dict(zip(range(3), [df['col'].apply(lambda x : x.split(' ')[i]) for i ...
