The asterisk will match zero or more characters, so any file ending in. exec on Unix-like systems, and enables you to do something similar on Windows platforms. Linting highlights syntactical and stylistic problems in your Python source code, which oftentimes helps you identify and correct subtle programming errors or unconventional coding practices that can lead to errors. You need to include header = None option to tell Python there is no column name (header) in data.

ReadAsArray() method can be used to read raster data as numerical arrays, ready to use with the Python numerical array capabilities. A good way to remember the difference between a backslash and a forward slash is that a backslash leans backwards ( \ ), while a forward slash leans forward ( / ). The Internet URL path separator was chosen to be the slash since most of the developers of the standards where familiar with Unix.
