In short, the aware object should be used in dealing with time data with timezone. Naive objects are easy to understand and to work with, at the cost of ignoring some aspects of reality. Whether a naive object represents Coordinated Universal Time (UTC), local time, or time in some other timezone is purely up to the program, just like it is up to the program whether a particular number represents metres, miles, or mass. An aware object is used to represent a specific moment in time that is not open to interpretationĪ naive object does not contain enough information to unambiguously locate itself relative to other date/time objects. The official Python document says as below,Īn aware object has sufficient knowledge of applicable algorithmic and political time adjustments, such as time zone and daylight saving time information, to locate itself relative to other aware objects. In dealing with date and time in Python, keep in mind two kind of data naive and aware. Sample code with fromtimestamp function is as bellow.Ĥ 5 tzinfos = Ħ date_str = ' 20:10:56' 7 str_to_dt = parse(date_str + ' JST', tzinfos =tzinfos)Ĩ print(str_to_dt) Points to keep in mind when dealing with date and time naive and aware Using the fromtimestamp function in datetime module makes the code simpler as well. It is often the case that I judge it by digits or actual calculation by fuction. Just one thing to be careful of this conversion is to check whether the numeric types of epoch time is in second or millisecond. Therefore, the unix time is merely the number of seconds between a particular date and the Unix Epoch. The epoch time is also called as Unix time and this counts starts at the Unix Epoch on January 1st, 1970 at UTC. Now convert numeric data types of eopch time to datetime. There are three types to process date and time in Python. The indexing of character in a string starts from ‘0’, and therefore, the string's first character always has the index equal to zero.Because I always google the way to convert a string representing the date to datetime and change timezone on the Internet, this is note to self article. Square brackets are used to access the string elements along with the index position of the string character. In python, the string is a sequence of Unicode characters which include every character and symbol in all languages. Therefore, the characters you input in the system are converted into a binary format using the encoding techniques like Unicode and ASCII. Also, triple quotes are used to display the multi-line quotes.Īs you know, that computer does not deal with characters but instead, it works only with binary numbers. You can use single quotes or double quotes to display the string. What are strings in python?Ī string is a series of characters inside the quotes. Before understanding the methods to convert the string to float explicitly, let us first go through the strings and float data types in python. Hence, you have to explicitly convert the string into a floating-point value so that you can perform the necessary operations on it. Even though you ask for the floating-point value, the input method in python will fetch the user input as a string object. When you take a user input in python programming while working with terminal or file operations like reading or writing a file, the input is a string object.
