Hi all,
I am new in python (i am moving from Perl world), but I always love
Python for hight level, beatuful and clean syntax.
Now I have question/idea about working with files.
On mine opinion it very popular use case:
1. Open file (for read and write)
2. Read data from file
3. Modify data.
4. Rewrite file by modified data.
But now it is looks not so pythonic:
with open(filename, 'r+') as file:
data = file.read()
data = data.replace('old', 'new')
file.seek(0)
file.write(data)
file.truncate()
or something like this
with open(filename) as file:
data = file.read()
data = data.replace('old', 'new')
with open(filename) as file:
file.write(data)
I think best way is something like this
with open(filename, 'r+') as file:
data = file.read()
data = data.replace('old', 'new')
file.rewrite(data)
but for this io.BufferedIOBase must contain rewrite method
what you think about this?
