문자열 정렬

• ljust,center,rjust,zfill()

st.ljust(x)  좌측 정렬
st.center(x) 가운데 정렬
st.rjust(x)  우측 정렬

"01".rjsut(4,'0')
>>>"0001"

"01".ljsut(4,'0')
>>>"0100"

"2".zfill(4)
>>> "0002"

"512".zfill(4)
>>>"0512"

한 줄 코드....

solution = lambda n, arr1, arr2: ([''.join(map(lambda x: '#' if x=='1' else ' ', "{0:b}".format(row).zfill(n))) for row in (a|b for a, b in zip(arr1, arr2))])
