Hi, please write the code above in Python. Thanks a bunch!

LU DECOMPOSITION AND MATRIX INVERSION SUB Ludecomp (a, b, n, tol, x, er) DIM O.S. END IF END Decompose SUB Pivot (a, o.s. n. k) p=k big = ABS(@otk), k/50/k)) DOFOR 1 = K + 1. n dummy = ABS(11),/s() IF dummy > big THEN big = dummy p = 11 END IF END DO dummy = 0 0 = Ox 0 = dummy END Pivot er = 0 CALL Decompose(a, n, tol, 0, s. er) IF er -1 THEN CALL Substitute(a, o, n, b. x) END IF END Ludecomp SUB Decompose (a, n, tol, 0, s. er) DOFOR 1 = l. n 0 = 1 S; = ABS(2.1) DOFOR j = 2. n IF ABS(2.)>S, THEN S: - ABS(1) END DO END DO DOFOR k = 1 n - 1 CALL Pivot(a, 0, s. n. k) IF ABS(ark)k/Sock))
