本文实例讲述了python静态方法。分享给大家供大家参考。

具体实现方法如下：

复制代码 代码如下:

staticmethod Found at: builtin
staticmethod(function) -> method

Convert a function to be a static method.

A static method does not receive an implicit first argument.
To declare a static method, use this idiom:

class C:
def f(arg1, arg2, ...): ...
f = staticmethod(f)

It can be called either on the class (e.g. C.f()) or on an
instance
(e.g. C().f()). The instance is ignored except for its class.

Static methods in Python are similar to those found in
Java or C++.
For a more advanced concept, see the classmethod builtin.

class Employee:
"""Employee class with static method isCrowded"""

numberOfEmployees = 0 # number of Employees created
maxEmployees = 10 # maximum number of comfortable employees

def isCrowded():
"""Static method returns true if the employees are crowded"""

return Employee.numberOfEmployees > Employee.maxEmployees

create static method

isCrowded = staticmethod(isCrowded)

def init(self, firstName, lastName):
"""Employee constructor, takes first name and last name"""

self.first = firstName
self.last = lastName
Employee.numberOfEmployees += 1

def del(self):
"""Employee destructor"""

Employee.numberOfEmployees -= 1

def str(self):
"""String representation of Employee"""

return "%s %s" % (self.first, self.last)

main program

def main():
answers = [ "No", "Yes" ] # responses to isCrowded

employeeList = [] # list of objects of class Employee

print "Employees are crowded?",
print answers[ Employee.isCrowded() ]

print "\nCreating 11 objects of class Employee..."

for i in range(11):
employeeList.append(Employee("John", "Doe" + str(i)))

print "Employees are crowded?",
print answers[ employeeList[ i ].isCrowded() ]

print "\nRemoving one employee..."
del employeeList[ 0 ]

print "Employees are crowded?", answers[ Employee.isCrowded() ]

if name == "main":
main()

希望本文所述对大家的Python程序设计有所帮助。
