![]() ![]() If you want to learn more about the directives and strptime. One advantage of converting to date format is one can select the month or date or time individually. The first parameter is the string and the second is the date time format specifier. For this, we will perform the following steps. Using strptime (), date and time in string format can be converted to datetime type. import ast convert string representation of dict to dict ast. You can make changes to the global symbol table inside any scope to convert a string to a global variable name. You can use the ast.literaleval() function to convert the string representation of a dictionary to a dictionary in Python. When executed, the globals() function returns the global symbol table. For this task, you can use the globals() function. If you want to convert a string to a global variable when you are inside a function, you cannot do it using the locals() function. This will create the intermediate list of tuples and we will get a structured array of tuples as a result. If you use a dictionary, you must use ascii. To avoid this error, we will first convert the items of a dictionary into a list and then we will convert this list into numpy array using the array object. If a character is not specified in the dictionary/table, the character will not be replaced. Use the maketrans () method to create a mapping table. Convert String Into Variable Name in Python Using the globals() Method The translate () method returns a string where some specified characters are replaced with the character described in a dictionary, or in a mapping table. After that, you can add variables using the subscript notation or the _setitem_() method as shown in the previous examples. If you want to make changes in the global symbol table to convert a python string to a global variable name, you can execute the locals() function in the global scope. Output: The variables in global scope and their values are: Print("The variables in global scope and their values are:") You can observe this in the following python code. It is a global symbol table that contains all the names defined in the global scope of the program. In this, we perform the conversion of key-value pairs to the dictionary using a map, and splitting key-value pairs is done using split (). The combination of above functionalities can be used to perform this task. The globals() function, when executed, returns a dictionary that contains all the variable names as string literals and their corresponding values. Method 1 : Using map () + split () + loop. We can access the variable names in python using the globals() function and the locals() function. To convert a comma-separated string to a dictionary, use the str.split() method to split the string on each comma. Then, we have assigned the string “ PythonForBeginners” to myStr. Converting JSON files to a dictionary is quite an easy task in python as python script provides a built-in JSON module and JSON has a built-in load() function. ![]() In the above example, we have created a variable myStr. Output: The value in myStr is: PythonForBeginners We can define a string value and assign it to a string variable as shown in the following example. ![]() We can also define strings using triple quotation marks. A python string is a literal contained within single quotes or double-quotes. ![]()
