I'm creating a program which will eventually have like 500 calls for print
function, and some others too. Each of these functions will take the exact same parameters every time, like this:
print(a, end='-', sep='.')
print(b, end='-', sep='.')
print(c, end='-', sep='.')
print(..., end='-', sep='.')
Is there a way to change the default values of print
function's parameters? So that I wouldn't have to type end='-', sep='.'
every time?
You can define a special version of print()
using functools.partial()
to give it default arguments:
from functools import partial
myprint = partial(print, end='-', sep='.')
and myprint()
will then use those defaults throughout your code:
myprint(a)
myprint(b)
myprint(c)
You can also use a lambda function:
my_print = lambda x: print(x, end='-', sep='-')
my_print(a)
my_print(b)
my_print(c)
还有一种方法允许多个参数并与 lambda 一起使用:
my_print = lambda *args: print(*args, end="-", sep=".")
