Given an integer (`n`), where `n` is between 1 and 1000 (inclusive), return the `n`th decimal of π. - Make sure to return a number not a string. π with its first five decimals is 3.14159. So given `5` for example, return `9`, the fifth decimal. You may have to find the first 1000 decimals of π somewhere. # --hints-- `get_pi_decimal(5)` should return `9`. ```js ({test: () => { runPython(` from unittest import TestCase TestCase().assertEqual(get_pi_decimal(5), 9)`) }}) ``` `get_pi_decimal(10)` should return `5`. ```js ({test: () => { runPython(` from unittest import TestCase TestCase().assertEqual(get_pi_decimal(10), 5)`) }}) ``` `get_pi_decimal(22)` should return `6`. ```js ({test: () => { runPython(` from unittest import TestCase TestCase().assertEqual(get_pi_decimal(22), 6)`) }}) ``` `get_pi_decimal(39)` should return `7`. ```js ({test: () => { runPython(` from unittest import TestCase TestCase().assertEqual(get_pi_decimal(39), 7)`) }}) ``` `get_pi_decimal(76)` should return `2`. ```js ({test: () => { runPython(` from unittest import TestCase TestCase().assertEqual(get_pi_decimal(76), 2)`) }}) ``` `get_pi_decimal(384)` should return `4`. ```js ({test: () => { runPython(` from unittest import TestCase TestCase().assertEqual(get_pi_decimal(384), 4)`) }}) ``` `get_pi_decimal(601)` should return `0`. ```js ({test: () => { runPython(` from unittest import TestCase TestCase().assertEqual(get_pi_decimal(601), 0)`) }}) ``` `get_pi_decimal(1000)` should return `9`. ```js ({test: () => { runPython(` from unittest import TestCase TestCase().assertEqual(get_pi_decimal(1000), 9)`) }}) ``` # --seed-- ## --seed-contents-- ```py def get_pi_decimal(n): return n ``` # --solutions-- ```py def get_pi_decimal(n): pi = "31415926535897932384626433832795028841971693993751058209749445923078164062862089986280348253421170679821480865132823066470938446095505822317253594081284811174502841027019385211055596446229489549303819644288109756659334461284756482337867831652712019091456485669234603486104543266482133936072602491412737245870066063155881748815209209628292540917153643678925903600113305305488204665213841469519415116094330572703657595919530921861173819326117931051185480744623799627495673518857527248912279381830119491298336733624406566430860213949463952247371907021798609437027705392171762931767523846748184676694051320005681271452635608277857713427577896091736371787214684409012249534301465495853710507922796892589235420199561121290219608640344181598136297747713099605187072113499999983729780499510597317328160963185950244594553469083026425223082533446850352619311881710100031378387528865875332083814206171776691473035982534904287554687311595628638823537875937519577818577805321712268066130019278766111959092164201989" return int(pi[n]) ```
