Is there something similar to pythons try: except: in roblox?

Im wonder if roblox has something like pythons
try:
print(“hi”
except:
warn(“error”)

the try except function is where in the try, you put in your code and if theres an error instead of stopping the script it goes to the except: where u put a print saying it errored or something

Like @whatplayer5858 mentioned, use pcalls.

local success, output = pcall(function()
   --.. do something
end)

if success then
   -- it was successful
else
   warn(output) -- send the error
end

you can use xpcall() for that

xpcall(function()

end, function()
    -- this function will run if the function above throws an error
end)

You’d use pcalls or (more preferably) xpcalls.

function source(a, b)
    assert type(a) == "number"
    assert type(b) == "number"
    return a + b
end

function msgh(msg)
    warn("Error Occurred: " .. msg)
    return nil
end

xpcall(source, msgh, 1, 2)
xpcall(source, msgh, "test", 2)
