</source>When using passing arguments up to functions in Python accept arguments, you MUST contain data such as '''strings''', '''numbers''', numerical values or '''variable names ''' within the function's '''brackets'''immediately following the function name.<br><br>'''NOTE: ''' Normally, when a function is declared that accepts arguments, those '''arguments must be declared ''' (using variable names). Those declared variable names are then used in within the function for processing. Also, when you call a function with arguments, the number of arguments passed up to the function must correspond (match) the number of arguments that were specified in the function declaration.<br><br>
