In Python Variables are just the labels that are pointing to the values. They don't carry any built-in metadata about their names. That's why there is no direct built-in method to get the variable name as a string. However, we can achieve this, by inspecting the environment such as ...
In Python 2.x The following example makes use of the iteritems() function to get a variable name as a string in Python. 1 2 3 4 5 6 # Python 2 code x = 7 x = [ i for i, a in locals().iteritems() if a == x][0] print("The variable name:", x) The above code pr...
# Variable name and value as stringsvariable_name="dynamicVar"value=42# Constructing and executing the string as Python codeexec(f"{variable_name} = {value}")# Access and print the newly created variableprint(dynamicVar) In our code, we start by defining two strings:variable_name, which is...
While programming in python, there are several instances when we might need to convert a string to a variable name. For instance, consider that we need to take some user data as input where the user needs to enter some field names and their corresponding values. We will need to convert th...
The{}placeholders in the string are filled in by the values ofvariable_nameandvalueusing an f-string. The resulting code is equivalent to writingdynamic_var = 'Hello'in our Python script. Finally, we print the value of the dynamically created variable usingprint(dynamic_var). ...
在Python中,我们可以使用import ... as ...语法将一个变量导入为模块名。具体的语法如下所示: importvariable_nameasmodule_name 1. 其中,variable_name是要导入的变量名,module_name是给导入的变量起的模块名。通过这种方式,我们可以在程序中使用module_name来访问variable_name的值。
We can use differentvariable namesin python programming. This can be one letter like a, b, x etc., one more letter or a combination of letters, digits and underscore character (_). Avariable namecan start with a lower case, upper case or underscore character. But a python variable name...
