 2. FizzBuzz

print(' '.join(["fizz"[x % 3 * 4:]+"buzz"[x % 5 * 4:] or str(x) for x in range(1, 101)]))

3. Primes between 1 and 100

print(' '.join([str(item) for item in filter(lambda x: not [x % i for i in range(2, x) if x % i == 0], range(2, 101))]))
print(' '.join([str(item) for item in filter(lambda x: all(map(lambda p: x % p != 0, range(2, x))), range(2, 101))]))

4. Nine multiplication tables

print('
'.join([' '.join(['%s*%s=%-2s' % (y, x, x*y) for y in range(1, x+1)]) for x in range(1, 10)]))

5. Flatten List

flatten = lambda x: [y for l in x for y in flatten(l)] if isinstance(x, list) else [x]

6. 

print(sum(map(int, str(2**1000))))

7. Print Fibonacci

print([x[0] for x in [(a[i][0], a.append([a[i][1], a[i][0]+a[i][1]])) for a in ([[1, 1]], ) for i in range(30)]])

8. Quick Sort

qsort = lambda arr: len(arr) > 1 and qsort(list(filter(lambda x: x <= arr[0], arr[1:]))) + arr[0:1] + qsort(list(filter(lambda x: x > arr[0], arr[1:]))) or arr

9. Eight Queens

[__import__('sys').stdout.write('
'.join('.' * i + 'Q' + '.' * (8-i-1) for i in vec) + "
========
") for vec in __import__('itertools').permutations(range(8)) if 8 == len(set(vec[i]+i for i in range(8))) == len(set(vec[i]-i for i in range(8)))]

10. Generate primes in one line: (181222)

reduce((lambda r,x: r-set(range(x**2,N,x)) if (x in r) else r), range(2,N), set(range(2,N)))
