Support in and logical operators
in is useful for all collections: convert e in s to a standard method call to <SequenceType>#contains?
No error handling for Go
Compiling the following program to Go produces no error handling logic:
import sys
print(int(sys.argv[1]))package main
import (
"strconv"
"os"
"fmt"
)
func main() {
_int, _ := strconv.Atoi(os.Args[1]) // error handling missing
fmt.Println(_int)
}When we go run foo.go "not_an_int", the program prints 0 and exists successfully. When we python3 foo.py "not_an_int", we see:
Traceback (most recent call last):
File "foo.py", line 3, in <module>
print(int(sys.argv[1]))
ValueError: invalid literal for int() with base 10: 'not_an_int'
Pow operator produces incorrect Go translation
Python's pow operator (x**2) produces math.Pow(x, 2) in Go; however, in Go, math.Pow() only accepts floats, but in Python, ** handles ints as well as floats. This means the Python program:
x = 2
print(x**2)Translates to
// package decl and imports elided
func main() {
x := 2 // int
fmt.Println(math.Pow(x, 2))
}Which fails to compile with error: ./foo.go:10: cannot use x (type int) as type float64 in argument to math.Pow
Support sys.stdin and sys.stdout
import sys
print(sys.stdin.readline())Error:

doesn't produce AST on Python3.5 from simple fib.py sample
I can't get it to read a file (I wanted to see the AST generated).
I'm on Mac OS 10.10.4 using Python 3.5.1 from homebrew.
Versions:
ivan@probook ~> pip3 freeze
pseudo==0.2.3
pseudo-python==0.2.6
Sample file;
ivan@probook ~> cat fib.py
def fib(n):
if n <= 1:
return 1
else:
return fib(n - 1) + fib(n - 2)
print(fib(4))
Expected to produce AST, but instead:
ivan@probook ~> pseudo-python fib.py
