and tofile() from the NumPy library, or the to_scv() from Pandas library. We can also use csv module functions such as writerow(). The savetxt saves a 1D or 2D array to a text file, The tofile() writes array data to a file in binary format, The writer() writes a single ...

To write a raw binary file with NumPy array data, we can simply change the data type of the array to int16 using the astype() method and then we can use the tofile() method to save the content into a binary file. The tofile() method writes an array to a file as text or ...
Using the Java NIO package, we can write to a file in a very concise manner, that is, typing less code. Example 1: import java.nio.file.{Paths, Files} import java.nio.charset.StandardCharsets object MyObject { def main(args: Array[String]) { val inputText = "I remembered black ...
