print(helloworlddid you notice how the text color changed to black when you removed the quotation marksidle no longer recognizes helloworld as text what do you think will happen when you run the programpress to find outthe following text displays in red in the interactive windowtraceback (most recent call last)file "/home/hello_world py"line in print(helloworldnameerrorname 'hellois not defined whenever an error occurspython stops executing the program and displays several lines of text called traceback the traceback shows useful information about the error tracebacks are best read from the bottom upthe last line of the traceback tells you the name of the error and the error message in this casea nameerror occurred because the name hello is not defined anywhere the second to last line shows you the code that produced the error there' only one line of code in hello_world pyso it' not hard to guess where the problem is this information is more helpful for larger files the third to last line tells you the name of the file and the line number so you can go to the exact spot in your code where the error occurred in the next sectionyou'll see how to define names for values in your code before you move onthoughyou can get some practice with syntax errors and runtime errors by working on the review exercises
