Question

python3

Continue from the previous function, write a draw_table method which draws a table of data. For example, consider the following code fragment:

my_table = Table([['Alice', 24], ['Bob', 19]], width=10)
my_table.draw_table()

produces:

|Alice     24        |
|Bob       19        |

Note: the column width is the value set up by the constructor. Insert a space in between columns.

and my previous function is

class Table:
def __init__(self,x, h = None, width=5):
self.x= x
self.h = h
self.w= width
def __str__(self):
return "headers={}, width={}, data={}".format(self.h,self.w,self.x)

Python program to create and test a class Table

class Table:

              

               def __init__(self,x, h = None, width=5):

                              self.x= x

                              self.h = h

                              self.w= width

                             

               def __str__(self):

                              return "headers={}, width={}, data={}".format(self.h,self.w,self.x)

                             

               def draw_table(self):      

                              # loop over the x

                              for item in self.x:

                                             print('|',end ='') # print the starting |

                                             # loop over the item

                                             for i in range(len(item)):

                                                            # print the ith position in item

                                                            # ljust returns a space padded string with the original string left-justified to a given width colum

                                                            print((str(item[i])).ljust(self.w,' '),end='')

                                             print('|') # print the ending |

              

# test the function

my_table = Table([['Alice', 24], ['Bob', 19]], width=10)

my_table.draw_table()   

                                            

#end of program
