[QUOTE=RMartins;537916]but how can i prove for example that the result of sqrt(n) is an integer?[/QUOTE] You can do this (maybe is there more elegant way) [CODE] if math.sqrt(n) == float(int(math.sqrt(n))): print "sqrt(n) is an integer" [/CODE]

Just a quick point. To turn an object into string, you can define the special method __repr__ in your object : [CODE] class myobject: def __init__(self, name): self.name=name def __repr__(self): return "my name is %s" % (self.name) o=myobject("toto") print o > toto [/CODE]

I'd write [CODE] self.cursor.execute("INSERT INTO DatabaseName (C1, C2, C3, C4, C5) SELECT (C1, C2, C3, C4, C5) FROM DatabaseName WHERE C1='%s'", [newC1Value]) [/CODE]

This code goes recursively in all the sudirs of your rootdir. Open all the files, read the lines, calls a function to process your line (here, it does nothing) and overwrite your files with your new lines [code=python] import os rootdir='c:\Your\Path' def doWhatYouWant(line): return line for subdir, dirs, files in …

Another method [CODE] import fnmatch pattern = '*.rtf' files = ['doc.txt', 'stuff.rtf', 'artfunction.exe', 'rtfunc.bat', 'doc2.rtf'] print('\n'.join(filename for filename in fnmatch.filter(files, pattern))) [/CODE]

A classical method using list comprehensions [CODE] dict([(list[i], list[i+1]) for i in range(0, len(list), 2)]) [/CODE] function dict takes a list of tuples for arguments and uses the first term of the tuple as key and the second as value If you need more explanations, don't hesitate to ask.

Here are some function you can look at : - os.listdir(mydir) will list all the files from "mydir" - fnmatch.filter(files_list, "*.txt") will give you a list of all text files in the files_list (tip : fnmatch.filter(os.listdir(mydir)) - os.path.join(mydir, file) will give you the absolute name of the file - os.walk(mydir) …

Hi, You can use () to make it work (if you really want a one liner)... [CODE] def l(): return (lambda ...)() [/CODE] [CODE] def l(): return (lambda x=input("Enter the text to be decrypted: "),y=int(input("Enter the shift amount: ")): print("The decrypted text is: "+"".join(list(map(lambda x: chr(ord(x)+y),x)))))() [/CODE]

Can you put the code you use for writing the content of the chest (i suppose : chest.printChest()) and the datas that are written ? BTW, for this kind of thing, you should have a look at __repr__ function.

This should work (not tested) [CODE] of = open(my_out_filename, 'w') for line in open(my_in_filename,'r'): if 'STRING' in line or 'INTEGER' in line: of.write(line) of.close() [/CODE]

You can generate csv files... For an easy csv management, there is a csv module [url]http://docs.python.org/library/csv.html[/url]

don't forget that, in os.walk, if you remove a dir from "dirs", it's subtree won't be explored. So [code] for dirpath, dirs, files in os.walk(path): for d in dirs: if d.startswith('.'): dirs.remove(d) # d's subtree won't be explored for f in files: if not f.startswith('.'): process_file() [/code]

A better way to deal with text files is rather with for loop : [code] of=open(myoutfilename, 'w') for line in open(myfilename,'r'): print line of.write(line.replace(' ', '\t')) of.close() ######### OR ############## # not sure the 2 with on the same line work (and i can't test it right now) # this …

Just one thing. For line iterating, i find it is a bad idea to load the whole file in a list (using readlines()) except if you can't process it sequentially. This will consume memory for really nothing interesting... Python allows iterating directly on file lines : [CODE] for line in …
