Is it possible to define a function name with #define?

wish helps you In your code WAITINGFUNC expands to void waitingfor. This is as expected when you're declaring a function, but isn't when you're calling it. So, in main function, you essentially have this:
code :
void main()
{
    void waitingfor(3);
}

this will help I want to define inline function within alert class currently i have following implementation. , You mean you want to do this? (Extremely bad idea):
code :
Alert.show('my mesage', 'header message', Alert.OK, Alert.No, function(event:CloseEvent):void
{
    //some code
});

it fixes the issue I think your explanation is a bit misleading: in both cases, you will have a top-level require call with a data-main attribute specifying a file to kick-start the process of requiring different modules.
So typically you will have this in your HTML:
code :
<script data-main="app/config" src="assets/js/libs/require.js"></script>
require.config({
  paths: {
    jquery:      '../assets/js/libs/jquery'
  }
});
require(['app']);
define(['module/first', 'module/second', 'module/third'], function (firstModule, secondModule, thirdModule) {
  // use firstModule, secondModule, thirdModule here
});
define(function(require) {
  var firstModule = require('modules/first');
  var secondModule = require('modules/second');
  var thirdModule = require('modules/third');
  // use firstModule, secondModule, thirdModule here

}
define(['jquery', 'underscore', 'backbone', 'modules/first', 'modules/second', 'modules/third', 'i18n', 'someOtherModule'], function ($, _, Backbone, first, second, third, I18n, someOtherModule) {
  // ...
});
define(function(require) {
  var $ = require('jquery');
  var _ = require('underscore');
  var Backbone = require('backbone');
  var firstModule = require('modules/first');
  var secondModule = require('modules/second');
  var thirdModule = require('modules/third');
  var I18n = require('i18n');
  var someOtherModule = require('someOtherModule');
  // ...
}

like below fixes the issue The Data is local variable which is only available in function readcsv(x), you could return it in the function and assign the result to variable Data, then you can use the variable Data. Like this:
code :
def readcsv(x): #def function to read csv files based on input below
    Data = pd.read_csv(x, parse_dates=['Time_Stamp'], infer_datetime_format=True)
    Data['Date'] = Data.Time_Stamp.dt.date 
    Data['Time'] = Data.Time_Stamp.dt.time 

    Data['Time_Stamp'] = pd.to_datetime(Data['Time_Stamp']) 
    print(Data[1:6])
    return Data

Data = readcsv('MainD.csv')

around this issue After asking this question a coworker I was pointed to this question on unix stackexchange: Unix Stackexchange question The way this problem was solved can be broken down to following lines:
code :
DEFINES=()
DEFINES+=(--define "dist .el7")
DEFINES+=(--define "foo bar")
/usr/bin/mock --init -r epel-7-x86_64 "${DEFINES[@]}"

around this issue All that's missing is a value to your definition.
Just add it and you can start testing the feature.
code :
#include <iostream>

#define SOME_DEFINE 42

void do_all_the_things() {
  std::cout << "woohoo!" << std::endl;
}

void do_none_of_the_things() {
  std::cout << "darn" << std::endl;
}

template <class T>
void foo(T param) {
  if (param == SOME_DEFINE) {
    do_all_the_things();
  } else {
    do_none_of_the_things();
  }
}

int main() {
  foo(42);
  foo(3);
  return 0;
}
const char* a = "value a";
const char* b = "value b";
return a == b;
#include <iostream>
#include <cstring>

#define SOME_DEFINE "test value"

void do_all_the_things() {
  std::cout << "woohoo!" << std::endl;
}

void do_none_of_the_things() {
  std::cout << "dang it" << std::endl;
}

template <class T>
struct AreEqual final {
  bool operator () (T a, T b) const {
    return a == b;
  }
};

template <>
struct AreEqual<const char*> final {
  bool operator () (const char* a, const char* b) const {
    return std::strcmp(a, b) == 0;
  }
};

template <class T, class AreEqualTo = AreEqual<T>>
void foo(T param, AreEqualTo are_equal_to = AreEqualTo()) {
  if (are_equal_to(param, SOME_DEFINE)) {
    do_all_the_things();
  } else {
    do_none_of_the_things();
  }
}

int main() {
  foo("test");
  foo("test value");
  return 0;
}
