Python allows you to use the popular data interchange format calledJSON (JavaScript Object Notation). The standard module calledjsoncan take Python data hierarchies, and convert them to string representations;
Output: $ python io_pickle.py ['apple', 'mango', 'carrot'] How It Works To store an object in a file, we have to first open the file in write binary mode and then call the dump function of the pickle module. This process is called pickling. Next, we retrieve the object using ...
file = open('output.txt', 'w') print("This will go into the file.", file=file) 运行上面代码,可以得到 2,利用print进行格式化输出 在Python中,可以使用字符串的format()方法或者f-strings(Python 3.6+)来对print()函数进行格式化输出。 下面是一些常用的格式化方法 (1)使用format() 方法 format()方法...
