How do I change the current working directory in Python?
If you use spyder and love GUI, you can simply click on the folder button on the upper right corner of your screen and navigate through folders/directories you want as current directory. After doing so you can go to the file explorer tab of the window in spyder IDE and you can see all the files/folders present there. to check your current working directory go to the console of spyder IDE and simply type
pwd
it will print the same path as you have selected before.
