Help me please, how I can write two action in the body of the cycle "for"?

For example, if I need to write Print[] and Append[] at each iteration.

  • $\begingroup$ @GThompson but also don't use For. It's slower, more work, and buggier than the many, many more powerful alternatives. $\endgroup$ – b3m2a1 Jun 10 '19 at 0:41

You can use CompoundExpression (;) (expressions separated by ;) in any argument of For:

For[i = 0; a = {}, i < 4, i++, Print[i]; AppendTo[a, i]]
