If you are using Python 3.6 and above,f-stringsmethod can be used. Thefletter indicates that the string is used for the purpose of formatting. It is the same as the simpleprintmethod in Python. However, in this method, we will use curly braces to indicate our variables. The variable we...
We have discussed ways to handle variables and thebest practices for naming variables in Python. We have noticed a number of searches on the site for how to return or print multiple variables in Python. Printing multiple variables in Python is quite simple. We are focused on Python 3 with a...

以装饰器的形式使用该工具,其包含了四个参数,参数包括output, variables, depth, prefix,如下图。 1、output参数。该参数指定函数运行过程中产生的中间结果的保存位置,若该值为空,则将中间结果输出到控制台。 2、variables参数。该参数是vector类型, 因为在默认情况下,装饰器只跟踪局部变量,要跟踪非局部变量,则可以...
在Python中,可以使用变量来指定print函数的文件名。以下是一个示例代码: 代码语言:python 代码运行次数:0 复制Cloud Studio 代码运行 filename = "output.txt" with open(filename, "w") as file: print("Hello, world!", file=file) 在这个示例中,我们首先定义了一个变量filename,它的值是output.txt。
Print Variable Name With a Dictionary in Python As discussed above, bothglobals()andlocals()functions return a dictionary that maps variables to their values. We can replicate that same functionality by creating a dictionary that contains variable names and their corresponding values in the form of...
