【问题描述】:
在变量y 中,我只想调用第二个值,即age,同时将第一个值(height)保持为默认值。我该怎么做?
class person():
def __init__(self, height=130, age=20):
self.height = height
self.age = age
def convert_height(self):
return self.height / 10
def find_birth_year(self, p_year):
return p_year - self.age
x = person(170)
y = person(, 32) # How to have default value for height here?
print(x.height, x.age)
print(y.height, y.age)
print(x.convert_height(), x.find_birth_year(2020))
print(y.convert_height(), y.find_birth_year(2020))
