From the Python 3 docs: The power operator has the same semantics as the built-in pow () function, when called with two arguments: it yields its left argument raised to the power of its right argument. The numeric arguments are first converted to a common type, and the result is of that type. It is equivalent to 2 16 = 65536, or pow(2, 16) Just ...
In Python this is simply =. To translate this pseudocode into Python you would need to know the data structures being referenced, and a bit more of the algorithm implementation. Some notes about psuedocode::= is the assignment operator or = in Python = is the equality operator or == in Python ; There are certain styles, and your mileage may vary:
When you iterate through dictionaries using the for .. in .. -syntax, it always iterates over the keys (the values are accessible using dictionary[key]). To iterate over key-value pairs, use the following: for k,v in dict.iteritems() in Python 2. for k,v in dict.items() in Python 3.
Here is the logical equivalent code in Python. This function takes a Python object and optional parameters for slicing and returns the start, stop, step, and slice length for the requested slice. def py_slice_get_indices_ex(obj, start=None, stop=None, step=None): length = len(obj) if step is None: step = 1.
you convert to Python native types that iterate the codes directly. On Python 3, it's trivial: for code in mystr.encode('ascii'): and on Python 2.6/2.7, it's only slightly more involved because it doesn't have a Py3 style bytes object (bytes is an alias for str, which iterates by character), but they do have bytearray:
Rather, the Python documentation website behind that link was rewritten. Apart from that, the documentation used to have stronger wording , and literally states that str.format “should be preferred to the % formatting”, just as I wrote in the comment you quoted.
It depends on how you want to access the import when you refer to it. from urllib import request. # access request directly. mine = request() import urllib.request. # used as urllib.request. mine = urllib.request() You can also alias things yourself when you import for simplicity or to avoid masking built ins:
Use the below sample script to get the current date and time in a Python script and print results on the screen. Create file getDateTime1.py with the below content. import datetime. currentDT = datetime.datetime.now() print (str(currentDT)) The output looks like below: 2018-03-01 17:03:46.759624.
s = s.rstrip() For whitespace on the left side, use str.lstrip: s = s.lstrip() You can provide an argument to strip arbitrary characters to any of these functions, like this: s = s.strip(' \t\n\r') This will strip any space, \t, \n, or \r characters from both sides of the string. The examples above only remove strings from the left-hand and ...
How can I convert a string into uppercase in Python? When I tried to research the problem, I found something about string.ascii_uppercase , but it couldn't solve the problem: >>> s = 'sdsd' >>> s.ascii_uppercase Traceback (most recent call last): File "<stdin>", line 1, in <module> AttributeError: 'str' object has no attribute 'ascii_uppercase'
