我们可以通过调用initialize_database函数来延迟创建数据库,以创建一个模块级变量: classDatabase:# the database implementationpassdatabase =Nonedefinitialize_database():globaldatabase database = Database() global关键字告诉 Python,initialize_database内部的数据库变量是我们刚刚定义的模块级变量。如果我们没有将...

Write a Python program to reverse a string. Sample String:"1234abcd" Expected Output:"dcba4321" Sample Solution-1: Python Code: # Define a function named 'string_reverse' that takes a string 'str1' as inputdefstring_reverse(str1):# Initialize an empty string 'rstr1' to store the rever...
package main import ( python "github.com/sbinet/go-python" ) func main() { python.Initialize() python.PyRun_SimpleString("print 'hello, world!'") python.Finalize() } 这看起来更接近普通 Go 代码,不再暴露 cgo,我们可以在访问 Python API 时来回使用 Go 字符串。嵌入式看起来功能强大且对开发人...

这被称为样板代码。例如,在清单 2-4 中,行public static void Main(String args[])和清单 2-5 ,public static void Main( )可能分别被归类为 Java 和 C# 端的样板代码。我们将在后面的章节中详细讨论这个概念。 现在,与 Java 相比,C# 对它的许多函数使用了不同的词汇。为了在屏幕上打印文本,我们有控制...
