Python 3.4 - Default Values for Arguments

Functions do things. Functions are made of arguments: "In mathematics, an argument of a function is a specific input in the function, also known as an independent variable. https://en.wikipedia.org/wiki/Argument_of_a_function

If I made a function called amount_of_hits_per_boxer I would need to arguments (name, hits)

The function would look something like this:

def amounts_of_hits_per_boxer(name, hits= 0):
    print(name, hits)

amounts_of_hits_per_boxer('Tyson =', 34)
 
The output would be Tyson = 34. By giving hits a default value of zero, if there is no input for hits, no 34, than we would just get a return of Tyson = 0. If you don't give arguments default values it can mess up our program, simply stated.

def get_gender(sex= 'Unknown'):
    if sex is 'm':
        sex = 'Male'    elif sex is 'f':
        sex = 'Female'    print(sex)

get_gender('m')
get_gender('f')
get_gender()

Pyhton 3.4 - Continue

Continue keeps the loop going. It allows you loop to do whatever else it wants to do outside of that statement. https://www.youtube.com/watch?v=68EhtQbgXRc Lakers_jerseys_taken = [ 8 , 24 , 32 , 34 ] print ( 'These are the jersey \' s still available:' ) for number in range ( 101 ): if number in Lakers_jerseys_taken: print ( 'You must be crazy' ) continue print (number)

Conversations Ongoing: Valuing Modernization in Early European History

Western scholarship has been known to focus on several metanarratives that define itself. These narratives can influence how we as historians view a certain time period, people, or event. Modernization in early European history can be seen as a major driving force in past and current scholarship. Influences of scientific progress, a fracturing Catholic Church, and growing capitalistic influences dominate the ideas scholars possess when viewing Europe during this time period. In regard to our own ideas about the narrative of modernization, its benefits and costs, one should be cognizant of this in viewing the social, economic, political and religious changes early "modern" Europeans faced.

Conversations Ongoing: A Bunch of Amateurs

Jack Hitt's a Bunch of Amateurs To analyze the American character one must take into account the narratives of our country, specifically the three metanarratives that it is based on. In Hitt's analysis of our national character he finds an endless list of examples stretching back to our early Vaudevillian days of americans striking out, trying to get-rich-quick, seemingly fearless in the face of overwhelming odds. I believe that piggy-backing onto the narratives of scientific progress, manifest destiny, and modernization one can easily get caught up in them. Cherry-picking evidence of those who have succeeded, painting a picture of our collective desire to innovate is troublesome. Simply put, I can create the opposite narrative quite easily. Many people in the USA have little to no interest in innovation, modernization, or the like. Quite the opposite. This place is much more than a collective bunch of amateurs but rather it includes them into the fold o...
