所以完整的代码是 print(string.replace("Python", "python"))。 输出结果将是 "python is good"。替换操作使得原来的 "Python" 变为了 "python",其他部分保持不变。 综上所述,答案为:string.replace("Python", "python") 本题考察了字符串的替换操作和字符串方法的使用。 相关知识包括: 字符串的替换...
“\n”表示换行,以r或R开头的字符串表示原始字符串,故print(r"\nGood")的运行结果是\nGood,故本题选C选项。 解析:C [详解] 本题主要考查Python输出语句。“\n”表示换行,以r或R开头的字符串表示原始字符串,故print(r"\nGood")的运行结果是\nGood,故本题选C选项。 二、程序填空...
Learn Python the Hard Way: A Good First ProgramArthur Kevin McGrath
Python libraries are crucial in building a foundation for machine learning and artificial intelligence. Mastering these libraries prepares learners for advanced data science by enabling them to organize and analyze large data sets effectively, ultimately enhancing decision-making processes. But what is it ...
Well, I think the libraries and framework Python offers e.g. PyBrain, NumPy and PyMySQL on AI, DataScience, and Machine learning are one of that reason. Another reason is diversity, Python experience allows you to do a lot more than R e.g. you can create scripts to automate stuff, ...
