Best Machine Learning Book for Beginners

You need a mixof different technologies for Data Science projects. Instead of learning many skills, just learn a few. The four main steps of any project are extracting the data, model development, artificial intelligence, and presentation. Attending interviews with many skills is not so easy. So keep the skills short.
A person with many skills can't perform all the work. You had better learn a few skills like Python, MATLAB, Tableau, and RDBMS. So that you can get a job quickly in the data-science project.
Out of Data Science skills, Machine learning is a new concept. Why because you can learn Python, like any other language. Tableau also the same. Here is the area that needs your 60% effort is Machine learning.  Machine Learning best book to start.

Python IF Statements Multiple Conditions Examples

I shared how to write multiple if conditions (statements) in Python. These are the best examples useful for interviews and projects.

Many programmers confuse how to write IF conditions in Python. The below examples act as a handy guide for beginners and experienced.

Python IF Statements the Best Examples


  1. IF, IF
  2. IF 'ELSE'
  3. IF 'or'
  4. IF 'and'
  5. Nested IF
  6. IF 'continue'
  7. IF 'break'

In Python,  the decision making logic you can write with IF condition. You can write multiple IF conditions (Single way decision). At the same time, you can write IF and ELSE conditions (Two-way decision).

Python IF Statements Multiple Conditions Examples

 

Multiple IF conditions the best example.

def main(): 
       celsius = float(input("What is the Celsius temperature? ")) 
       fahrenheit = 9/5 * celsius + 32 
       print("The temperature is", fahrenheit, "degrees Fahrenheit.")
 # Print warnings for extreme temps 
     if fahrenheit > 90: 
          print("It's really hot out there. Be careful!") 
     if fahrenheit < 30: 
          print("Brrrrr. Be sure to dress warmly!")
 

Note:  Writing IF conditions like this we call it a Single way of Decision. 

IF-Else condition the best example.


def main(): 
      print("This program finds the real solutions to a quadratic\n") 
      a = float(input("Enter coefficient a: ")) 
      b = float(input("Enter coefficient b: ")) 
      c = float(input("Enter coefficient c: ")) 
      discrim = b * b - 4 * a * c 
     if discrim < 0: 
          print("\nThe equation has no real roots!") 
     else: 
         discRoot = math.sqrt(b * b - 4 * a * c) 
         root1 = (-b + discRoot) / (2 * a) 
         root2 = (-b - discRoot) / (2 * a) 
         print("\n The solutions are:", root1, root2

Note: Writing IF conditions like this we call it Two way of Decision.

 

Nested IF condition the best example.

if condition:
	if condition:
		statements
	else:
		statements
else:
statements


 IF Continue condition the best example.


Notes: 'Continue' just continue the next iteration of the loop.

>>> for num in range(2, 10):
...     if num % 2 == 0:
...         print "Found an even number", num
...         continue
...     print "Found a number", num
Found an even number 2
....
 

IF break conditions the best example.


>>> for n in range(2, 10):
...     for x in range(2, n):
...         if n % x == 0:
...             print n, 'equals', x, '*', n/x
...             break
...     else:
...         # loop fell through without finding a factor
...         print n, 'is a prime number'
...
 

IF True Best Example.


flag = True
if flag:
    print("Welcome")
    print("To")
    print("BeginnersBook.com")

IF 'and' the Best Example.

if((a>b and a>c) and (a != b and a != c)): 
    print(a, " is the largest") 
elif((b>a and b>c) and (b != a and b != c)): 
    print(b, " is the largest") 
elif((c>a and c>b) and (c != a and c != b)): 
    print(c, " is the largest") 
else: 
    print("entered numbers are equal"
