fileinput.Fileinput .read() function for entire file

Question

Is there a way in fileinput.Fileinput (or some other module/class) where I can read the entire file into memory so I can replace a block of text from the file with a block of text in a list (saved in memory).

There is a .readline function, but I need to find & replace a block of text, and I would prefer not having to zip through the block of text line by line in parallel with zipping through the file.

Answer 1

Yes, file objects have a read method that reads the entire file contents into memory.

with open("myfile.txt") as infile:
    text = infile.read()

# manipulate text here

with open("myfile.txt", "w") as outfile:
    outfile.write(text)
