In rounding jargon, this is called truncating the number to the third decimal place. There’s some error to be expected here, but by keeping three decimal places, this error couldn’t be substantial. Right?To run your experiment using Python, you start by writing a truncate() function that...
In this article, I explained how toconvertfloat to int in Python. I discussed eight important methods, such as using theint()function, theround()methods, and type conversion in calculation. I also discussed how to handleedge cases, comparison of methods, real-worldexamples, convert the user ...

There are three main approaches to coding in Python. You already used one of them, the Python interactive interpreter, also known as the read-evaluate-print loop (REPL). Even though the REPL is quite useful for trying out small pieces of code and experimenting, you can’t save your code ...
To overwrite a file in Python, the “open()” method, “seek() and truncate()”, “re.sub()”, “os.remove()”, “replace()”, and “fileinput()” methods are used. The “open()” method is opened in write mode to overwrite the file in Python. The “os.remove()” function...

TheTRUNC() functiontakes a single number as an input and returns the integer part of the number. For example, if you enter truncate(12.345), Python returns 12 because the number 12.345 is rounded down to 12, and the decimal value is dropped. This is interesting because, essentially, without...
Overwrite a File in Python Using the file.seek() and file.truncate() MethodIn this session, we will focus on a more nuanced technique involving the seek() and truncate() methods. This approach is particularly useful when you need to read the file before overwriting it....
