Spaces in Paths

This is an update of the previous post originally created on April 20, 2016.

A number of readers have recently written me about an error they see when attempting to compile or execute an application or script in books such as, C++ All-In-One for Dummies, 4th EditionBeginning Programming with Python For Dummies, 2nd Edition, Python for Data Science for Dummies, and Machine Learning for Dummies, 2nd Edition. Development environments often handle spaces differently because they’re designed to perform tasks such as compiling applications and running scripts. When you see an error message that tells you that a file or path isn’t found, you need to start looking at the path and determine whether it contains any spaces. The best option is to create a directory to hold your source code and to place that directory off the root directory of your drive if at all possible. Keeping the path small and simple is your best way to avoid potential problems compiling code or running scripts.

The problem for many readers is that the error message is buried inside a whole bunch of nonsensical looking text. The output from your compiler or interpreter can contain all sorts of useful debugging information, such as a complete listing of calls that the compiler, interpreter, or application made. However, unless you know how to read this information, which is often arcane at best, it looks like gobbledygook. Simply keep scanning through the output until you see something that humans can read and understand. More often than not, you see an error message that helps you understand what went wrong, such as not being able to find a file or path. Please let me know if you ever have problems making the code examples in my books work, but also be sure to save yourself some time and effort by reading those error messages. Let me know if you have any thoughts or concerns about spaces in directory paths at [email protected].
