error: Couldn't open C:\python27\PyGame\resources\images\dude.png
What should I do?

Answer 1

First, make sure the file exists.
Next, using single backslashes, \, may lead to problems. For example, \r is the carriage return sequence (\n is the more widely known newline sequence). Your file path, happens to contain a \r, which could be causing your issue.
Try one of these instead:
# Use forward slashes
pygame.image.load("C:/python27/PyGame/resources/images/dude.png")
# Use double back-slashes. For file path specification, \\ indicates '\' (depending
# on the platform)
pygame.image.load("C:\\python27\\PyGame\\resources\\images\\dude.png")
# Use the os module
# Note that this assembles a path relative to your .py file.
# Absolute path can still be done here, it's just more verbose.
pygame.image.load(os.path.join("Pygame", "resources", "images", "dude.png"))
The last option is probably the best practice.
