increment

Is it possible to increment a for loop inside of the loop in python 3? for example: for i in range(0, len(foo_list)): if foo_list[i] < bar i += 4 Where the loop counter i gets incremented by 4 if the condition holds true, else it will just increment by one (or whatever the step value is for the for loop)? I know a while loop would be more applicable for an application like this, but it would be good to know if this (or something like this) in a for loop is possible. Thanks! You could use a while loop and increment i based on the condition: while i < (len(foo_list)): if foo_list[i] < bar: # if

a is an array, foo is a function, and i is an int . a[++i] = foo(a[i-1], a[i]); Would the code above, have an Undefined Behavior ? The array indices ++i , i-1 and i , are guaranteed to be in the array range. The behavior is undefined, but it's not because of the modification of the same object twice between two sequence points but it is UB because the side effect on i is unsequnced relative to the value computation of a[i-1] and a[i] using i . §6.5-p(2): If a side effect on a scalar object is unsequenced relative to either a different side effect on the same scalar object or a value

Defined this way, we can do neither ++x++ nor ++x-- . But on the other hand, both (++x)++ and (++x)-- are useful expressions: (++x)++ increments x by two and returns the value "in the middle", while (++x)-- is essentially equivalent to x+1 but completely avoids having to call operator+ , which can be quite useful sometimes. So why is the precedence not defined to have ++x++ automatically expand to (++x)++ rather than ++(x++) ? Is there some hidden meaning to the latter which I don't understand, or is it just to keep the precedence a simple list with all prefix operators making up one single

for example i have about 500 lines. in the beginning of each line i want to add a number. so in line 1 i would want "1)" and then line 2 i would want "2)" i know i can do a macro in n++, but it wouldn't be incremental. is there any possible way to do this? Notepad++ Macros only playback keyboard actions. They can't do anything dynamic. However there is a built-in(?) plugin that can do this for you. Highlight all the code, then choose "TextFX / TextFX Tools / Insert Line Numbers" One thing to be aware of is that it is the absolute line number within the file. You can't start numbering on line
