 Invalid Syntax Error on Import
#1
Hey All,

I am a beginner in Python and I am still in the learning stage. While I was learning an Example of Dual Mode code in my book, I came across the code below which I coded in a file as is but when I run it, it gives me an 'Invalid Syntax' error and highlights the import coded towards the end (Line 54). I tried running the file through command prompt, IDLE, checked indentation but to no avail. I am sure I am probably missing something very silly but can anyone please help.

You are missing close parens at the end of line 53. With a syntax error, it's good to check the line before as well as the line indicated.

Don't worry. We've all been there, and will be there again.
