How to Write a Calculator in 1 Python Line print input() > 25*4-50 > 50

  It accepts more than just numbers though: >>> print input() "a"+"b" ab

    try:print(lambda x:eval(x)if all(i in'0123456789.*/+-'for i in x)else'syntax error')(raw_input()) except:print'error'

    Mathematically, this is wrong.. a + b is not ab.

      It's not symbolic...
      • readme 14y ago
        Of course. I understand that "a" + "b" when taken to mean "concatenate the strings" is "ab" but OP's post was a calculator. It would not have yielded this result.

  Q. How to write code? A. I don't need to; other people will write it for me. That's fine, I guess. I prefer to understand.

    How to get things done? Use existing tools unless they are not suitable.

  Or, from a bash command line, $ python -c "print input('> ')" > 2+3*5 17
