Examples

Word frequency

import sys

with open(sys.argv[1]) as f:
    text = f.read()

counts = {}
for word in text.split():
    counts[word] = counts.get(word, 0) + 1

for word in sorted(counts, key=lambda w: counts[w]):
    print(word, counts[word])

pyscriptc compile wordfreq.py -o wordfreq
./wordfreq input.txt

Fibonacci

def fib(n: int) -> int:
    a, b = 0, 1
    for _ in range(n):
        a, b = b, a + b
    return a


print(fib(30))

Exit codes and argv

import sys

if len(sys.argv) < 2:
    print("usage: tool FILE")
    sys.exit(2)

with open(sys.argv[1]) as f:
    print(len(f.read().split()))
