print(any(list)) # will return True because there is 1 or True exists. print(all(list)) # will return False because there is a 0 or False exists. return all(a % i for i in range(3, int(a ** 0.5) + 1)) # when number is divisible it will return False else return True but the whole statement is False .
Dec 26, 2015 · Now what should the result be? Should the condition be true when one value is true? Should the condition be true only when all values are true? That’s exactly what numpy.any and numpy.all do. The former requires at least one true value, the latter requires that all values are true: >>> np.any(valeur <= 0.6) True >>> np.all(valeur <= 0.6) False
all and any are functions that take some iterable and return True, if. in the case of all, no values in the iterable are falsy; in the case of any, at least one value is truthy. A value x is falsy iff bool(x) == False. A value x is truthy iff bool(x) == True.
Sep 4, 2008 · It is a list of strings defining what symbols in a module will be exported when from <module> import * is used on the module. For example, the following code in a foo.py explicitly exports the symbols bar and baz: __all__ = ['bar', 'baz'] waz = 5. bar = 10. def baz(): return 'baz'. These symbols can then be imported like so:
Feb 14, 2011 · I very very strongly disagree with the statement, "shouldn't." You should do it sparingly. There are times when you're dealing with third party libraries (sometimes dynamically loaded!!) that have gone totally crazy with exceptions and tracking them all down can be a very painful task, and if you miss just one, you have a very very huge painful bug in your system.

Aug 12, 2019 · To get all column name you can iterate over the data_all2.columns. columns = data_all2.columns for col in columns: print col You will get all column names. Or you can store all column names to another list variable and then print list.
Oct 1, 2016 · All string characters are unicode literal in Python 3; as a consequence, since str.split() splits on all white space characters, that means it splits on unicode white space characters. So split + join syntax (as in 1 , 2 , 3 ) will produce the same output as re.sub with the UNICODE flag (as in 4 ); in fact, the UNICODE flag is redundant here (as in 2 , 5 , 6 , 7 ).
Almost all of the python files should live in their respective folders (C:\Python26 and C:\Python27). Some installers (ActiveState) will also associate .py* files and add the python path to %PATH% with an install if you tick the "use this as the default installation" box.
Jun 9, 2011 · Using np.where on an array (including the time to convert the list to an array) is slightly slower than a list-comprehension on a list, for finding all indices of all unique elements. This has been tested on an 2M element list with 4 unique values, and the size of the list/array and number of unique elements will have an impact.
