Python: ShowData

showdata.py

# This function prints out all of the values and sub-values in any variable, including 
# lists, tuples and classes. It's not very efficient, so use it for testing/debugging
# purposes only. Examples are below:

#-------------------------------------------------------------------------------------

# ShowData(range(10))

# (list)
#    (int) 0
#    (int) 1
#    (int) 2
#    (int) 3
#    (int) 4
#    (int) 5
#    (int) 6
#    (int) 7
#    (int) 8
#    (int) 9

#-------------------------------------------------------------------------------------

# ShowData([[j for j in range(1, i)] for i in range(1, 5)])

# (list)
#
#    (list)
#
#    (list)
#       (int) 1
#
#    (list)
#       (int) 1
#       (int) 2
#
#    (list)
#       (int) 1
#       (int) 2
#       (int) 3

#---------------------------------------------------------------------------------------

# class example:
# 	x = 5
# 	y = 10.24
# 	z = 43.5
#
# ShowData(example())

# (instance)
#    (dict pair)(str)y : (float)10.24
#    (dict pair)(str)x : (int)5
#    (dict pair)(str)z : (float)43.5

#----------------------------------------------------------------------------------------

#(or use the 'index' keyword argument to show list indicies)
# ShowData(range(10), index=True)

# (list)
#   [0](int) 0
#   [1](int) 1
#   [2](int) 2
#   [3](int) 3
#   [4](int) 4
#   [5](int) 5
#   [6](int) 6
#   [7](int) 7
#   [8](int) 8
#   [9](int) 9


# Returns "int"/"float"/"list", etc.
