PyCharm的“simplify chained comparison”是什么？
PyCharm的“simplify chained comparison”是什么？
我有以下函数，PyCharm在elif语句上发出了警告，提到了“simplify chained comparison”。代码可以正常工作，我得到了我想要的对象，只是想知道这个警告是什么意思，以及如何更好地写代码？
def preferred_contacts(self):
x = random.randint(0, 100)
email = u'E'
text = u'M'
phone = u'P'
letter = u'L'
none = u'N'
if x < 25: return email elif x >= 26 and x <= 50: return text elif x >= 51 and x <= 75: return phone elif x >= 76 and x <= 100:
return letter
else:
return none

更简化的方法链调用，使代码更清晰。请看下面
def preferred_contacts(self):
x = random.randint(0, 100)
email = u'E'
text = u'M'
phone = u'P'
letter = u'L'
none = u'N'
if x < 25:
return email
elif 26 <= x <= 50: # reads as "x is between 26 and 50, inclusive
return text
elif 51 <= x <= 75: # reads as "x is between 51 and 75, inclusive
return phone
elif 76 <= x <= 100: # reads as "x is between 76 and 100, inclusive
return letter
else:
return none
