7,454 PointsQuotation Problem
I wrote:
print('Enter 'q' to quit.')
When I get a syntax error I corrected it to:
print(r'Enter 'q' to quit.')
Yet I get the same error. Why? I thought that this "r" will solve quotation problem in a string. I have written the code below to solve the problem:
print("Enter 'q' to quit.")

To escape quotes of the same style as the string quotes use a backslash:
print('Enter \'q\' to quit.')

Why do I get this? Why does it have two backslashes?
