本文實例講述了python靜態(tài)方法。分享給大家供大家參考。

具體實現(xiàn)方法如下：

復制代碼 代碼如下: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

# call static method using class

print "Employees are crowded?",

print answers[ Employee.isCrowded() ]

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

# create 11 objects of class Employee

for i in range(11):

employeeList.append(Employee("John", "Doe" + str(i)))

# call static method using object

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()

希望本文所述對大家的Python程序設計有所幫助。
