Python

Integers and Floats

Integer = number
int (pi) ==3
Float = decimal number
float(answer) == 42.0

Strings

String = text
"Hello World"

"hello" .capitalize() == "Hello"
"hello" .replace("e" ,"a" ) == "hallo"
"hello" .isalpha() == True
"123" .isdigit() == True 
"some,csv,values" .split(",") == ["some", "csv", "values"]

name = "Martin"machine = "Hal"print ("Nice to meet you {0}. I am {1}".format(name,machine))

Boolean and None

python_course = True

int (python_course) == 1

If Statements

number = 5

if number == 5:

      print ("Number is 5")

else:

      print ("Number is NOT 5")

Lists (mutable, ordered)

student_names = ["John", "Paul", "George","Ringo"]

student_names[0] == "John"
! List values start at 1
student_names[-1] == "Ringo"

! Minus sign reads values from the right of the list

len(student_names) == 4

del student_names[2]

! Remove George from list

Dictionaries (mutable, associative array)

Device = {"hostname":"router1","OS":"v15.5,"location":"London")

Tuple (sequence of immutable objects)

Credentials = ("hostname","username","password")

Sets (unordered collection of unique and immutable objects) 

Loops

for name in student_names

     print ("Student name is {0}" .format(name))

For Loop

student_names = ["John", "Paul", "George","Ringo"]

for name in student_names:

  if name == "John":

  print("Found him! " + name)

  break
