Find the least common multiple of an array of numbers

#!/usr/bin/python3
import sys
from math import gcd

def lcm_list(nums):
    from functools import reduce
    def lcm(a, b):
        return a * b // gcd(a, b)
    return reduce(lcm, nums)

nums = list(map(int, sys.argv[1:]))
print(lcm_list(nums))

Print a range of unicode characters

#!/usr/bin/python3
import sys
a = int(sys.argv[1],16)
b = int(sys.argv[2],16)
for i in range(a,b + 1):
    print(" ".join([str(hex(i))," ",chr(i)]))

Make the first field of standard input uppercase:

python3 -c "import sys;[print(l.split()[0].upper(),*l.split()[1:]) for l in sys.stdin]"
