To writes the array in the file, I have used the file.write().The bytearray() method returns the byte array objects. And assigned an array as num= to get the array in byte converted format, I have used bytearray().In this example, I have opened a file as array.bin and used the “wb” mode to write the binary file.Here, we can see how to read a binary file to an array in Python. You may like Python Pandas CSV Tutorial and File does not exist Python. Here, from the sentence, it will read only four words. In this output, you can see that I have used print(file.read(4)). The read() method returns the specified number of bytes from the file.Įxample to read the file: file = open('document.bin','rb') To read the file, I have taken the already created file document.bin and used the “rb” mode to read the binary file.Sentence = bytearray('This is good'.encode('ascii')) And then to close the file, I have used the file.close().Įxample to write the file: file = open('document.bin','wb') The write() is used to write the specified text to the file.And to write the sentence in the file, I have used the file.write() method.

I have taken a variable as a sentence and assigned a sentence “This is good”, To decode the sentence, I have used sentence = bytearray(“This is good”.encode(“ascii”)).The document.bin is the name of the file.In this example, I have opened a file using file = open(“document.bin”,”wb”) and used the “wb” mode to write the binary file. Before reading a file we have to write the file.Here, we will see how to read a binary file in Python. Python read a binary file into a NumPy array.Python read a binary file into a byte array.
