solve in python only, all the test cases should pass. AI is giving wrong answers!!!!!!

here are the test cases:

testcase$1$:

text $=($

$"$

lol some text I guess

$"$

"here is the first paragraph

$"$

$"$

here is the second one

$"$

"some words here in the third one

$"$

"this is the last line

$"$

$)$

assert move$\_$cursor$((1,0),$ text, $"2\}")==(7,0)$

assert move$\_$cursor$((1,0),$ text, $"2\}3$W$")==(8,12)$

assert move$\_$cursor$((1,0),$ text, $"2\}3$WG$")==(9,12)$

testcase$2$:

text $=($

$"$

lol some text I guess

$"$

"here is the first paragraph

$"$

$"$

here is the second one

$"$

"some words here in the third one

$"$

"this is the last line

$"$

$)$

try:

move$\_$cursor$((1,1),$ text, $"2\}3$WG$")$

except ValueError:

# first line is empty, there's no $(1,1)$

pass

assert move$\_$cursor$((1,0),$ text, $"2\}")==$ move$\_$cursor$((1,0),$ text, $"\}\}")$

testcase$3$:

$"$

$)$

assert $($

move$\_$cursor$((3,1),$ text, $"$hhhhhhhhhhhhhhhhhhhhhhhhhhh$")$

$==$ move$\_$cursor$((3,1),$ text, $"30$h$")$

$==(3,27)$

$)$

testcase$4$:
