  • Implement python replace() function without using regexp

    - by jwesonga
    I'm trying to rewrite the equivalent of the python replace() function without using regexp. Using this code, i've managed to get it to work with single chars, but not with more than one character: def Replacer(self, find_char, replace_char): s = [] for char in self.base_string: if char == find_char: char = replace_char #print char s.append(char) s = ''.join(s) my_string.Replacer('a','E') Anybody have any pointers how to make this work with more than one character? example: my_string.Replacer('kl', 'lll')

  • stored values within a custom function

    - by romunov
    My program takes a data.frame and crunches the numbers. At one point, values from j-th column are multiplied by a predefined values that depends on the column name (species name, actually - it's en ecological index). So far, I've been providing these values via a second data.frame by matching column names. What would be an efficient way of integrating fixed variable values within a function? I would like my program to be as portable as possible, without the need for a second data.frame file.

  • Function overloading in C

    - by Andrei Ciobanu
    Today, looking at the man page for open(), I've noticed this function is 'overloaded': int open(const char *pathname, int flags); int open(const char *pathname, int flags, mode_t mode); I didn't thought it's possible on C. What's the 'trick' for achieving this ?

  • C++ choose function by return type.

    - by anon
    I realize standard C++ only picks functions by argument type, not return type. I.e I can do something like: void func(int); void func(double); but not double func(); int func(); Where in the former, it's clear, in the latter, it's ambigious. Are there any extensions that lets me tell C++ to pick which function to use also by return type? Thanks!

  • Good practice of using list of function in Python

    - by riskio
    I am pretty new to python and I discovered by myself that I can create a list of function and call with a for loop. example: def a(args): print "A" def b(args): print "B" def c(args): print "C " + str(args) functions = [a,b,c] for i in functions: i(1) So, my question is: is there any good practice or elegant way to use list of functions and what is a good use of all this? (do have a particular name the "list of functions"?) thank you

    - by VaioIsBorn
    Let say i have some words AB, AAB, AA. AB is not a prefix to AAB but AA is a prefix to AAB because if i just add B at the end of AA it will become AAB, which is not possible with AB. So, is there any function in c++ (STL) so that i can determine of two words if one is prefix to the another ? Thanks.
