print("Name: {}, Age: {}".format(name, age)) str.format()方法更加灵活,可以支持多种格式化要求,并且语义更加清晰。 使用f-string name = "Charlie" age = 35 print(f"Name: {name}, Age: {age}") f-string是一种简洁的格式化方式,支持在字符串中直接嵌入表达式,是Python 3.6之后的推荐方法。 四...
针对以上的问题,可以使用 Python 的内置模块inspect来输出变量名。以下是实现这一功能的 Python 代码示例: importinspectdefprint_variable_name(variable):frame=inspect.currentframe().f_back variable_name=[nameforname,valueinframe.f_locals.items()ifvalueisvariable]print(variable_name[0]ifvariable_nameelse"Va...

Python provides multiple ways to format strings in print(). Using F-Strings (Python 3.6+): F-strings provide an efficient way to embed expressions within string literals. name="Tom"age=25print(f"Hello,{name}. You are{age}years old.") ...
python 2(或<3.3) 它们没有将flush参数反向移植到python 2.7,因此如果您使用的是python 2(或小于3.3),并且想要与2和3兼容的代码,我建议您使用以下兼容代码。(注意,EDOCX1[9]导入必须位于/非常"靠近模块顶部"): 1 2 3 4 5 6 7 8 9 10 11

With this approach, you can continue to use both unbuffered and bufferedprint()calls. You also define up front that you’ll use unbuffered writes to standard output. You even give the function a descriptive name, which might make it quicker for other developers to grasp what you’re doing ...

We got an error. The error is "name 'ToolsQA' is not defined". What's that error, and how can we resolve it? It is related to the concept ofliteralsandvariables. We will study it in detail in subsequent articles, however, let's quickly touch base it here. ...
