Hello, guys! I am new to Julia. Help me please. I want to change my string initialized in upper local scope, and then use it there text = "abacaba" text_result = "" #string must be changed for rule in 1:5 if i % 2 == 1 #some condition text_result = replace(text, "a" => "b", count=1) #t…

To re-assign the global variable text_result you need global in the loop. I highly recommend creating a function around this loop with text_result as an input (in which case you do not need global).

If the loop is not inside a function you need to declare test_results as a global AFAIK: text = "abacaba" text_result = "" #string must be changed for rule in 1:5 if i % 2 == 1 #some condition global text_result = replace(text, "a" => "b", count=1) #this is another string end end pr…

[image] ExpandingMan: I highly recommend creating a function around this loop with text_result as an input (in which case you do not need global ). Why would you use text_result as an input? Strings are immutable, so you cannot change them. The scoping issue seems to me a red herring. for ru…
