Partial

Partial function operators allow you to quickly create a new function by binding some parameters. Compared with the standard library functools.partial, it is more flexible and powerful.

Grammar

f(?, 2)

f(?, ?, 3, ?)

f(a, b=?)

f(*?, b=10)

f(name="Aber", **?)

Each ? means to add a positional parameter to the generated function.

Trick

When you need to pass a sequence, but only want to pass a parameter using a pipe (|>), please use *?.

Try to see the difference between ("hello", "world") |> print(?) and ("hello", "world") |> print(*?).
