Embedded Distribution New in version 3.5. The embedded distribution is a ZIP file containing a minimal Python environment. It is intended for acting as part of another application, rather than being directly accessed by end-users. When extracted, the embedded distribution is (almost) fully isolated from the user’s system, including environment variables, system registry settings, and installed packages. The standard library is included as pre-compiled and optimized .pyc files in a ZIP, and python3.dll, python35.dll, python.exe and pythonw.exe are all provided. Tcl/tk (including all dependants, such as Idle), pip and the Python documentation are not included. Note The embedded distribution does not include the Microsoft C Runtime and it is the responsibility of the application installer to provide this. The runtime may have already been installed on a user’s system previously or automatically via Windows Update, and can be detected by finding ucrtbase.dll in the system directory. Third-party packages should be installed by the application installer alongside the embedded distribution. Using pip to manage dependencies as for a regular Python installation is not supported with this distribution, though with some care it may be possible to include and use pip for automatic updates. In general, third-party packages should be treated as part of the application (“vendoring”) so that the developer can ensure compatibility with newer versions before providing updates to users. The two recommended use cases for this distribution are described below -- Luuk -- https://mail.python.org/mailman/listinfo/python-list

Re: "min( arg1, arg2, *args )" vs. "print( value, ... )"?
On 6-4-2020 22:57, Stefan Ram wrote:
The documentation ("help" under CPython 3.9) for "min" reads
(simplified):
min( arg1, arg2, *args )
, for "print" it reads (simplified):
print( value, ... ).
The caller can place an arbitrary number of arguments at the
place of "value, ..." or of "*args", respectively.
So, from the point of view of the caller: is there any
difference between "args, ..." and "*args" when he reads
it in the documentation?
`arg1, arg2, *args` is just a smart way to say you need at least 2 args.

The first line is a simple print statement to print the text "hallo"

In the second line i added a '\' (backslash), the letter 'a' seems to be
missing, unless audio on your computer works. If audio works you will
hear a bell.
(see: https://docs.python.org/2.0/ref/strings.html )
In the third line a 'r' is put in front of the string, and now the 'a'
is shown again (and also the '\').
In your path there is something like '...programs\assertion\CNN..'.
Python does see a '\a', after 'programs', and before 'ssertion', and

Re: Need help (Basic python)...what did I do wrong?
frankie_85 [EMAIL PROTECTED] schreef in bericht news:[EMAIL PROTECTED] Hi everyone, I just made a simple code which is part of my assignment but I can't figure it out what's wrong with it. (always give me error messages) What the code basically does is: a function that takes one floating point number x as its argument and returns (the square root of the absolute value of x) plus (5 times x cubed). and read 5 floating point values from the user into a list then apply the function to each value in the list and print the results in reverse order. import math print Enter 5 values: a = float(raw_input()) b = float(raw_input()) c = float(raw_input()) d = float(raw_input()) e = float(raw_input()) def funct(a, b, c, d, e): a_1 = math.sqrt(math.fabs(a)) + 5((math.pow(a,3))) b_2 = math.sqrt(math.fabs(b)) + 5((math.pow(b,3))) c_3 = math.sqrt(math.fabs(c)) + 5((math.pow(c,3))) d_4 = math.sqrt(math.fabs(d)) + 5((math.pow(d,3))) e_5 = math.sqrt(math.fabs(e)) + 5((math.pow(e,3))) return a_1 return b_2 return c_3 return d_4 return e_5 print e_5, d_4, c_3, b_2, a_1 funct(a, b, c, d, e) it always gives me these error messages: Traceback (most recent call last): File /Users/x/Documents/test3.py, line 25, in module funct(a, b, c, d, e) File /Users/x/Documents/test3.py, line 11, in funct a_1 = math.sqrt(math.fabs(a)) + 5((math.pow(a,3))) TypeError: 'int' object is not callable What did I do wrong? Please help me Thanks in advance obviously the error is in the line a_1 = math.sqrt(math.fabs(a)) + 5((math.pow(a,3))) try changin this to a_1 = math.sqrt(math.fabs(a)) + 5*math.pow(a,3) because you seem to want 5 time the result of the pow() function -- http://mail.python.org/mailman/listinfo/python-list

Is there a more efficient method to find a string in a text file then:
f=file('somefile')
for line in f:
if 'string' in line:
print 'FOUND'
yes, more efficient would be:
grep (http://www.gnu.org/software/grep/)

ok, a more serious answer:
some googling turned op the following.
Second paragraph of chapter 14 of http://www.amk.ca/python/2.1/
a.. The speed of line-oriented file I/O has been improved because people
often complain about its lack of speed, and because it's often been used as
a naïve benchmark. The readline() method of file objects has therefore been
rewritten to be much faster. The exact amount of the speedup will vary from
platform to platform depending on how slow the C library's getc() was, but
is around 66%, and potentially much faster on some particular operating
systems. Tim Peters did much of the benchmarking and coding for this change,
motivated by a discussion in comp.lang.python.
A new module and method for file objects was also added, contributed by Jeff
Epler. The new method, xreadlines(), is similar to the existing xrange()
built-in. xreadlines() returns an opaque sequence object that only supports
being iterated over, reading a line on every iteration but not reading the
entire file into memory as the existing readlines() method does. You'd use
it like this:
for line in sys.stdin.xreadlines():
# ... do something for each line ...
...
For a fuller discussion of the line I/O changes, see the python-dev summary
for January 1-15, 2001 at http://www.amk.ca/python/dev/2001-01-1.html.
