“Fetching Datetime From Float In Python” ~ bbaz
Python is a widely used programming language that provides developers with several tools to convert data types. One such conversion task that programmers often encounter is the conversion of float data into datetime objects. This article aims to explain and compare different methods from which Python developers can convert float to datetime with simple code.
Method 1: Using timedelta()
One way of converting float to datetime in Python is by making use of the timedelta() function available within the datetime module. The function returns a datetime object representing a duration, which can be further used for various operations. Here’s an example code snippet:
“`import datetimedef float_to_datetime(float_time): delta = datetime.timedelta(seconds=float_time) return datetime.datetime(1970, 1, 1) + delta print(float_to_datetime(1626301813.695932))“`
The above code generates a datetime object with the help of the timedelta() function passed with the float value of 1626301813.695932. It then uses this object to add the number of seconds to January 1st, 1970 using the + operator. The output of the code is:
The conversion process is straightforward since it makes use of built-in functions provided by Python. Additionally, using timedelta() helps make the code more readable and efficient for larger datasets since it involves fewer lines of code.
This method may not be suitable for datetime objects outside the range of January 1st, 1970 onward.
Method 2: Converting through int() and strftime()
The second method of converting a float to datetime objects involves converting the float into an integer using the int() function and then further converting it into a datetime object with strftime(). Here’s an example:
“`import datetimedef float_to_datetime(float_time): return datetime.datetime.strptime(datetime.datetime.fromtimestamp(float_time).strftime(‘%Y-%m-%d %H:%M:%S’), ‘%Y-%m-%d %H:%M:%S’) print(float_to_datetime(1626301813.695932))“`
The code first takes the float value and uses the fromtimestamp() function to convert it into a datetime object. Then, the object is converted into a string format and manipulated by strptime() to produce a final, clean datetime object. The output of the code above is:
This method can cover a wide range of datetime objects and provides ample room for formatting to suit individual needs.
The conversion process can be slower compared to other methods, particularly when working with larger datasets.
Method 3: Using dateutil.parser.parse()
A third method of converting float to datetime in Python is through the use of dateutil.parser.parse(). It is a powerful tool that can recognize several different string formats of datetime and convert them into a datetime object. Here is an example of how to use this method:
“`from dateutil.parser import parseprint(parse(1626301813.695932))“`
In this code, the parse() function recognizes the float as a Unix timestamp and converts it into a datetime object. The output would be:
This method can recognize and convert a wide variety of date and time formats, saving time and tedious coding work.
The use of external modules such as dateutil.parser can significantly increase runtime and take longer to process compared to other methods within the python datetime module.
Method 4: Using pandas.to_datetime()
Lastly, a popular data manipulation library, pandas, comes with its own set of conversion functions, including to_datetime(). This method is exceptionally adept at handling large datasets and unnecessary string manipulations. Here’s how it works:
“`import pandas as pdprint(pd.to_datetime(1626301813.695932, unit=’s’))“`
The line of code above takes a float and passes it through to_datetime() with the ‘unit’ parameter specifying the timestamp unit. The output of the code is as follows:
This method provides a fast and streamlined approach for converting a wide range of datatypes and timestamps within Pandas dataframes. This method is well documented, making it easy to understand and incorporate into larger datasets
If not working with frameworks that require the installation of pandas, this may not be a preferred method for programmers seeking to avoid the additional dependency required by Pandas.
Each approach presented in this article can help developers to easily and efficiently convert float to datetime objects in Python. Furthermore, each approach has its strengths depending on the size and makeup of the datasets being manipulated. Developers should consider the benefits and disadvantages of each method before selecting a conversion approach for their specific needs.
|Using timedelta() function||Less code required, suitable for smaller datasets||Bound to datetime objects from January 1st, 1970 onward|
|Converting through int() and strftime()||Covers a wide range of datetime objects, highly customizable through strftime()||Can be slow, especially for larger datasets|
|Using dateutil.parser.parse()||Recognizes and converts multiple date and time formats||Can be taxing on runtime and computational power compared to other inbuilt methods|
|Using pandas.to_datetime()||Efficient and robust when working with Pandas data frames||Requires installation of Pandas|

When working with Python, you may encounter situations where you need to convert a floating-point number to a datetime object. This can be a bit tricky, but it is definitely doable with just a few lines of code. Here are some common questions that people ask about converting float to datetime in Python:
What is a float in Python?
A float is a data type in Python that represents a decimal number. It is called a floating-point number because the decimal point can float to different positions depending on the magnitude of the number.
Why would I need to convert a float to a datetime?
In some cases, you may receive data in the form of a float that represents a timestamp or a date/time value. To perform any meaningful analysis or processing on this data, you will need to convert it to a datetime object.
How do I convert a float to a datetime in Python?
Here is a simple code snippet that shows how to convert a Unix timestamp (which is a float) to a datetime object:
- Import the datetime module:
- Define the Unix timestamp as a float:
timestamp = 1620669421.0
- Convert the timestamp to a datetime object:
dt_object = datetime.datetime.fromtimestamp(timestamp)
- Print the datetime object:
This will output the datetime object in the format
- Import the datetime module:
