Error when running mmap related function in python 2.6
I tried to run the following code from http://docs.python.org/library/mmap.html
import mmap # write a simple example file with open("hello.txt", "wb") as f: f.write("Hello Python!\n") with open("hello.txt", "r+b") as f: # memory-map the file, size 0 means whole file map = mmap.mmap(f.fileno(), 0) # read content via standard file methods print map.readline() # prints "Hello Python!" # read content via slice notation print m开发者_JAVA技巧ap[:5] # prints "Hello" # update content using slice notation; # note that new content must have same size map[6:] = " world!\n" # ... and read again using standard file methods map.seek(0) print map.readline() # prints "Hello world!" # close the map map.close()
But, I got an error.
TypeError: 'module' object is not callable module body in mmap.py at line 9 map = mmap.mmap(f.fileno(), 0)
What's wrong with this? I use python 2.6 on Snow Leopard/Mac.
I think you're doing something weird calling your module mmap.py
, and the import is getting confused and importing the same file instead... Try changing the name to something else (preferably not a standard library module name :p)
