mtTkinter allows multithreading with Tkinter, you can get it here: http://tkinter.unpythonic.net/wiki/mtTkinter Just import mtTkinter in place of Tkinter. This will allow you to insert text into a Text widget from multiple threads without conflict. I used it for some instant messaging software I wrote and it works wonderfully.
You opened the file for writing by specifying the mode as ‘w’; open the file for reading instead: ‘r’ is the default, so it can be omitted. If you need to both read and write, use the + mode: w+ opens the file for writing (truncates it to 0 bytes) but also lets you read from it. If you use r+ it … Read more
Shortest Code Example: Generally Speaking Explained: zip the two lists. create a new, sorted list based on the zip using sorted(). using a list comprehension extract the first elements of each pair from the sorted, zipped list. For more information on how to set\use the key parameter as well as the sorted function in general, take a look at this.
It’s working exactly as it’s supposed to. The transpose of a 1D array is still a 1D array! (If you’re used to matlab, it fundamentally doesn’t have a concept of a 1D array. Matlab’s “1D” arrays are 2D.) If you want to turn your 1D vector into a 2D array and then transpose it, just slice it with np.newaxis (or None, they’re … Read more
Using a regex Using a regex, you can clean everything inside <> : Some HTML texts can also contain entities that are not enclosed in brackets, such as ‘&nsbm‘. If that is the case, then you might want to write the regex as This link contains more details on this. Using BeautifulSoup You could also use BeautifulSoup additional package to find … Read more
When you say You are implicitly asking Python to convert (a[‘x’]==1) and (a[‘y’]==10) to Boolean values. NumPy arrays (of length greater than 1) and Pandas objects such as Series do not have a Boolean value — in other words, they raise ValueError: The truth value of an array is ambiguous. Use a.empty, a.any() or a.all(). when used as a … Read more
for any one has this problem: the key is that in anaconda3 pyuic5.bat is in: Anaconda3\Library\bin also the Designer is here. so in cmd you must first cd to: then:
I haven’t reproduced the issue, but perhaps this method would solve it: (writing line by line to stdout rather than using print) You could catch the broken pipe? This writes the file to stdout line by line until the pipe is closed. You also need to make sure that othercommand is reading from the pipe before it gets too big – https://unix.stackexchange.com/questions/11946/how-big-is-the-pipe-buffer
0 and 1 are the exit codes. exit(0) means a clean exit without any errors / problems exit(1) means there was some issue / error / problem and that is why the program is exiting. This is not Python specific and is pretty common. A non-zero exit code is treated as an abnormal exit, and at times, … Read more
My suggestion is to use a function. But rather than putting the if in the function, which you might be tempted to do, do it like this: (Yes, you can define a function in an if statement, and it’ll only get defined if the condition is true!) If you’re using Python 3, where print is already a function (or if you’re … Read more
