Not sure what your question is But I guess you are being tripped up by a pervasive and confusing pun which you are inadvertently(?) using in one line: a> i = i+1 b> 4+1 = 5 a> is an assignment statement IN the programming language python b> is a math statement ABOUT python a> in math is meaningless (unless i is ∞ or something) b> in programming is a syntax error If you feel you are confused thats good; most professional programmers are more confused and dont know it. The predecessor of python -- ABC -- wrote i = i+1 as PUT i+1 IN i Unfortunately python followed the mainstream and confusified it to i=i+1 -- https://mail.python.org/mailman/listinfo/python-list
