Descriptive statistics - mode(), mean() and median()

C. mode() - returns the value that appears most from a set of values. Example:- 1. import pandas as pd import pandas as pd df2 = pd.DataFrame({2016:{'q1':500,'q2':500,'q3':47000,'q4':49000},2017:{'q1':'A','q2':'A','q3':'A','q4':'D'},2018:{'q1':54500,'q2':51000}}) df2.mode() Output:- 2016 2017 2018 0 500.0 A 51000.0 1 NaN NaN 54500.0 Explanation:- Since by default axis=0 so mode is calculated among rows(indexes) i.e for each column. 2. df2.mode(axis=1) 0 1 2 q1 500 A 54500.0 q2 500 A 51000.0 q3 47000 A NaN q4 49000 D NaN Explanation:- Since axis=1 so the mode is calculated among columns i.e for each row. 3.  df2.mode(numeric_only=True) Output:- 2016 2018 0 500.0 51000.0 1 NaN 54500.0 Explanation: With numeric_only=True only numeric values are included for mode calculation and String/Text values are not considered.

Python Tokens

Tokens  or Lexical unit are the smallest buidling blocks of a program. Tokens are the equivalent of alphabets , grammer and tenses of a English language. Python has the following tokens:- Keywords Identifiers(Names) Literals Operators Punctuators a. Keywords - are the reserved words that has a special meaning and should be used only where its meant to be. Example:- False, True, for, while, None, break, if, elif, else b. Identifiers(Names) - The names given to different parts of the program like variables, function, objects, classes etc. eg:- a = 2, add(), here a and add are identifier names Rules for framing identifier names. Identifier name should be a combination of letters(a-z, A-Z) and digits(0-9). eg:- Valid names - abc123, abc, xy_123, xy_ Invalid names - abc#12, age$  First character must be a letter or underscore. eg:- Valid names- _123, a_123    Invalid names - 1abc Upper and lower case are different. eg:- ABC and abc are both different i...

Python Tokens - Operators

Operators - Tokens that trigger computation when applied to variables and other objects in a expression. Variable and expression to which the operators are applied are called operands. Example:- 2+3 here 2,3 are operands and + is operator. 1. Unary Operators -  It operates on only one operand. Example:- Operator Name Example + Unary Plus +10, 23E+2 - Unary Minus -4.3, -2.3E-1 ~ Bitwise complement ~3 not Logical negation not 2 2. Binary Operators - It requires two operators to operate upon. Operator Name Example + Addition 2+3 = 5 - Subtraction 2-3=-1 * Multiplication 2*3=6 / Division 2/3 = 0.66666666 % Remainder 2%3 = 2 ** Exponent 2**3 = 8 // Floor division 55//2 = 27
