Nothing bad at
Great Video! I would just like to know how you commented out a big chunk of code at :)
Great video,.Corey. quick question: how did you mark out the code at ? I am trying to put " in front of my code over 100 lines, any suggestions how that could be done in atom or pycharm?
Do you have a video on all the shortcuts you use when writing the code? For example, I just noticed at when you said, “let me comment out these lines”, then you highlighted the lines, and magically had them all commented out in one swift motion.I am super new, but learning those would be SUPER beneficial. Thanks!!
a little question, hope someone can answer, how to make scrips to become commants? and it be done vise-versa? like in , he had done
At for reading the file, a loop is done:
When he says that the code written as is would initiate an infinite loop at , would the output if he did run it just be the first 100 characters over and over again? (lines 1 through 5 of his test.txt) Or would it print the entire test.txt over and over?
Thanks for this tutorial, very practical, explaining how read() can cause a memory bottleneck if the file is huge. One question though ... unable to understand at how while loops executes its last iteration and exits. From the output its clear that only 4 characters remain to be read at the start of last iteration which is still greater than 0. Can someone elaborate?
for writing file . Np . Thanks for the vid man really helped me out in the write mode part <3
Writing to Files
Careful! File contents(if exists) are erased the moment it's opened in write mode.
Why did 'R'' did not overwrite 'Test' since it is 'write' command not 'append'?
at the for loop has statement: wf.write (line) > this must be in 'a' mode to keep all the lines copied to the newly generated file .. or I am missing something?
at , if you remove the text from the write file and re-run the program it does not write in the file again it just leaves it blank. In order to use the function to write into the file, I have to create a new write file. Why is this?
And, I have a little question @ of the video.
one of the reasons why liner algebra is useful in cs
first things first very thnks for your hard works your lessons very awesome , in i think you don't need loop you can just do like this:with open('bronx.jpg', 'rb') as rf:with open('copy_bronx.jpg', 'wb') as wf:wf.write(rf.read())
i dont understand how the while loop works here(), rf_chunk = rf.read(chunk_size) how this keep in not being in infinite loop.
