My string 下例能将关键字参数顺序不重要展示得更清楚: #!/usr/bin/python# -*- coding: UTF-8 -*- #可写函数说明def printinfo( name, age ): "打印任何传入的字符串" print "Name: ", name; print "Age ", age; return; #调用printinfo函数printinfo( age=50, name="miki" ); 以上实例输出...
string tuple range frozenset bytes mutable对象 与immutable对象对应的就是mutable对象,也就说对象的值是可变的,例如我我们熟知的append函数。 l =[] l.append(1)print("After l.append(1), the address of l:", id(l)) l.append(2)print("After l.append(2), the address of l:", id(l))#执行...
Python presents several immutable objects, including numbers, strings, and tuples. Let’s delve into a few examples: # Number my_num = 10 # Attempting to alter the value of an integer results in the creation of a new object # String my_str = 'Hello, world!' # Strings are also immuta...
python mutable python mutableset Python的数据类型分为mutable(可变)和immutable(不可变)mutable:list,dict一般情况下,程序员自定义的python类型都是mutable的,但是如果你想定制immutable的数据类型,那么你必须重写object的__setattr__和__delattr__方法immutable:int,string,float,tuple...由于python的变量(va pytho...
foo = [] id(foo) // same foo.append(3) id(foo) // same 1. 2. 3. 4. Immtuable such as string: str = "Hello" id(str) // not the same str = "World" id(str) // not the same 1. 2. 3. 4.
Example of an immutable data type (string): Code: str1 = "Python" new_str1 = str1.lower() # Creating a new string with all lowercase characters print(str1) # Output: "Python" (Original string remains unchanged) print(new_str1) # Output: "python" (New string with modifications) ...
