How do you know its a variable? x+1 Is that 1 the constant or l the variable? Yes, "use a better font" is good advice, if you can -- you don't always have control over the machine you are working on, and the fonts which you have access to -- but even with a better font, they still look two similar for comfort. It's just common sense[1] to avoid easily confusable names whenever possible: advice = 23 advise = 23 makenewhttpfactorywidgetcreator = True makenewhttpfactoryuidgetcreator = False regardless of how awesome your font is. Unless you're spelling out each word letter by letter, sometimes you will misread words. Another one is rn versus m, especially at small text sizes, or if you're silly or unlucky enough to be using Arial.
