11/17/2023 0 Comments Multiple python versions linuxWe just need to open the Windows command prompt, or Windows Powershell, and enter the command. In Windows operating systems, we can use the command python -version to check the python version.To learn more about the Python Programming Language, refer to the articles : Python 3 has no backward compatibility with the previous version i.e. With some effort, we can port the Python 2 code to Python 3. Python 3 is more popular than Python 3 but in some places, we still use Python 2. Python 2 is not longer in use since the year 2020. We use the range() function for iteration in Python 3. We used the xrange() function for iteration in Python 2. For example, 7/2 yields 3.5Įxception in Python 2 was dealt with in the enclosed notations.Įxceptions in Python 3 are enclosed in parentheses. The division of two integral values in Python 3 results in a floating-point value. The division of two integral values in Python 2 results in another integral value. The strings are by default stored as ASCII characters in Python 2. The strings are by default stored as UNICODE characters in Python 2. Python 3 interpreter considers print() as a function. Python 2 interpreter considers print as a statement but not a function. We can run a particular python program (or python script) using the specified Python interpreter version.įor example, if we have Python 2.6 and Python 3.6 installed on our system, then we can run a file (let's say program.py) using both interpreters. We can have multiple Python interpreter versions installed on our system. What if Your Computer has Multiple Python Versions Installed? We can easily upgrade to the latest or newer version of the Python interpreter by simply going to the (visiting) Python downloads page and downloading the latest version. It also returns additional information about the build number and the compiler used. version method returns a string that contains the version number of the Python interpreter installed in the system. version method in the sys (system) module to print the version of the Python interpreter installed on the system. I) Various information string: sys.version : Let us see the script and its related information. The script is very useful for checking the python version even tho we have various versions of Python installed on our system. The script will be the same for all operating systems such as Windows, Mac, Linux, etc. We can use the sys module or the platform module of the standard library to check the python version in various operating systems. Let us now learn how to check the python version using scripts. Which can be used for detailed information than -V or -version. The -VV option is a new command added since Python 3.6. All of these commands will provide a similar result. Note: We can use the commands such as python -version or python -v or python -VV.
