如何缩短基本字典的重复部分? [复制]
原标题:How to shorten a repetitive part of basic python code? [duplicate]

I am new to coding, and just started learning Python last week. I made this Powerball number generator to practice:

import random

print(random.randrange(1, 70))

import random

print(random.randrange(1,70))

import random

print(random.randrange(1, 70))

import random

print(random.randrange(1,70))

import random

print(random.randrange(1, 70))

import random

print(random.randrange(1,27))

www.un.org/spanish/ecosoc 我很想知道,我如何能够缩短这一时间,因为第5种“进口随机印刷”完全相同?

感谢前面的帮助。

问题回答

首先,在你第一次使用之前,你只需要随机进口。 这应当缩短:

import random

print(random.randrange(1, 70))

print(random.randrange(1,70))

print(random.randrange(1, 70))

print(random.randrange(1,70))

print(random.randrange(1, 70))

print(random.randrange(1,27))

那么,你可以在解决办法中创造像@mikeb所说的那样的 lo,从而进一步缩短:

import random

for i in range(4):
   print(random.randrange(1,70))

print(random.randrange(1,27))

此外,虽然与这一具体法典无关,但缩短载有重复守则的守则的共同办法是将守则置于类似职能中:

import random

def powerball(n):
    print(random.randrange(1, n))

for i in range(4):
    powerball(70)

powerball(27)

你可以这样做。

import random

for x in range(0, 5):
    print(random.randrange(1, 70))

另外,进口你也不得不多次进口。 你在档案中刚刚这样做了。 这里还有更多有关猪.的信息:。 https://www.w3schools.com/python/python_for_loops.asp

仅需要<代码>进口随机,而且你可以使用一种途径:

import random

for _ in range(0, 5): # 0, 1, 2, 3
  print(random.randrange(1, 70))

print(random.randrange(1,27))

注:_为有效变量名称,通常为您为未使用的变量名称所用名称。 在这种情况下,我们不注意我们所依赖的(范围生成者的价值),因此我们使用<条码>——,表明我们没有为此目的使用。
