string-formatting

I have a pandas DataFrame with mixed values in it. I am working in Ipython notebook while developing it. When displaying the dataframe I would like it to display to facilitate easier reading. At the moment I am using python string formatting to display all floats to 4 decimals and to add thousand separators. pd.options.display.float_format = '{:,.4f}'.format Ideally I would like to E.g. Display Values over 10000 without decimals, fractions with 4 significant digits etc. Is there a way that I can use the python string formatting syntax to achieve this? I know i can do it for individual column,

I am tring to return an int value with comma seperators within the value. 12345 would be returned as 12,345 The follwing code works: int myInt = 1234567; MessageBox.Show(string.Format("My number is {0}", myInt.ToString("#,#"))); 12,345 is displayed as expected. While the following code does no work, but from what I am reading, should work: int myInt = 1234567; MessageBox.Show(string.Format("My number is {0:#,#}", myInt.ToString())); 12345 is displayed. Can you help me understand why the second set of code is not working? Thanks You shouldn't ToString the int before the format. Try this:

I'm trying to format dates which I retrieve from my database table, I wanted to format from "2015 02 11 12 00" to "Feb 2" but it gives an error when I format it. Is there any other ways formatting those dates? Following the codes: protected String doInBackground(String... args) { // Building Parameters List<NameValuePair> params = new ArrayList<NameValuePair>(); // getting JSON string from URL JSONObject json = jParser.makeHttpRequest(url_all_events, "GET", params); // Check your log cat for JSON reponse Log.d("All events: ", json.toString()); try { // Checking for SUCCESS TAG int success =

Following code: def __init__(self, url, **kwargs): for key in kwargs.keys(): url = url.replace('%%s%' % key, str(kwargs[key])) Throws the following exception: File "/home/wells/py-mlb/lib/fetcher.py", line 25, in __init__ url = url.replace('%%s%' % key, str(kwargs[key])) ValueError: incomplete format The string has a format like: http://www.blah.com?id=%PLAYER_ID% What am I doing wrong? You probably want the format string %%%s%% instead of %%s% . Two consecutive % signs are interpreted as a literal % , so in your version, you have a literal % , a literal s , and then a lone % , which is

I am using the latest stable PyCharm 2016.1.4 and Python 3.6a1. Whenever I use the "f-strings" ( PEP-498 ) PyCharm is complaining about f being an unresolved reference : Is the literal string interpolation not supported by PyCharm yet? Or, should I have enabled or configured it separately? The Literal String Interpolation is now supported in PyCharm 2016.3 , the relevant feature request: PY-18972 implement support for PEP 498 (f-strings) Note that the stable 3.6 is scheduled to be released in December . 来源： https://stackoverflow.com/questions/38215059/pycharm-and-f-strings

I am a bit confused about the 'rules' of when a TextView element displays text in formatted form or not. A string like "There are <i>different ways</i> of coding.\n"; displays without any formatting (including the HTML codes) when I code tvMyTextView.setText("There are <i>different ways</i> of coding.\n"); but when I define the same string in strings.xml and then load tvMyTextView.setText(R.strings.TestString); it displays emphasized. Even more confused I feel when trying to embed URLs in TextView's like here: "Click <a href="http://www.poon-world.com">here</a> to switch on the red light.\n";

I like to format all numbers like in math. is there a predefined function or is that just possible with substring and replace? edit: my culture is de-ch Best regards Try this int input = Convert.ToInt32("1700"); string result = String.Format("{0:##,##}", input); Or this Console.WriteLine(1700.ToString("##,##", new NumberFormatInfo() { NumberGroupSeparator = "'" })); var numformat = new NumberFormatInfo { NumberGroupSeparator = "'", NumberGroupSizes = new int[] { 3 }, NumberDecimalSeparator = "." }; Console.WriteLine(1000000.ToString("N",numformat)); Try this: Console.WriteLine(1000000.ToString

I'm trying to use string.format on a 'nan' float. Here's the description of the 'g' option from the python documentation . General format. This prints the number as a fixed-point number, unless the number is too large, in which case it switches to 'e' exponent notation. Infinity and NaN values are formatted as inf, -inf and nan, respectively. And here's what i get trying it in the interpreter (Python 2.6): >>> print "{0:g}".format(float('nan')) -1.#IND As I understand the documentation, the output should be "nan". Is this a bug or am I doing it wrong? repr(float) was fixed in Python 2.6 and
