Minor Corrections

[Rajath Kumar]

covers chapters 00 - 04,

• example given not true for Python 3
  No requirement of defining as float initially in python 3
• indexing
  add reverse indexing? i.e grades[-1], grades[-2]
• help() command
  using help function, help() and with ?, jupyter notebook autocompletion using tab, and asking them to explore each function of every data structure
• any data structure or type possible inside a list
  showing examples of list inside a list for matrices?
• python 3 keeps the function as is
  range function defined as count, does not print the values
• add list of bitwise, comparison and logical operators?
• implicit arguments in functions
• Other data structures not discussed
• should be (1,0)
• print(numpy.linspace(-1, 1, 10))
• TODO: use %precision 3
• should not mention dtype=complex, is done in the following explanation
• use %matplotlib notebook made for Jupyter notebooks, plot becomes interactive
• add plt.colorbar()
• close bracket
• explaining list comprehension in previous chapters?
