and a .liquid file with some Python code

❯ cat python.liquid
───────┬───────────────────────────────────────────────────────────────────────────────────────────────────────────────
       │ File: python.liquid
───────┼───────────────────────────────────────────────────────────────────────────────────────────────────────────────
   1   │ #!/usr/bin/env python
   2   │
   3   │ def do_something(name, email):
   4   │   print("Hello " + name + ", Email: " + email)
   5   │
   6   │ def main():
   7   │   {%- for item in items %}
   8   │     do_something("{{ item.name }}", "{{ item.email }}")
   9   │   {%- endfor %}
  10   │
  11   │ if __name__ == "__main__":
  12   │   main()

You can do this:

❯ open people.csv | take 4 | codegen python.liquid
#!/usr/bin/env python

def do_something(name, email):
  print("Hello " + name + ", Email: " + email)

def main():
    do_something("Michael Brown", "[email protected]")
    do_something("Linda Rodriguez", "[email protected]")
    do_something("David Jones", "[email protected]")
    do_something("John Jackson", "[email protected]")

if __name__ == "__main__":
  main()
