Python Loops And Statements


while loop
when condition of given statements is True, while loop is execute.
Example:
i = 0
while i < 5:
  print(i)
  i += 1
Output:
0
1
2
3
4
Break and Continue Statements
*In Python, break and continue statements can alter the flow of a normal loop.
*Loops iterate over a block of code until test expression is false, but sometimes we wish to terminate the current iteration or even the whole loop without checking test expression.
*The break and continue statements are used in these cases.
While loop with break Statements:
Example:
i = 0
while i < 5:
  print(i)
  if i == 3:         #break the loop
    break
  i +=1
Output: 
0
1
2
3
While loop with continue Statements:
Example:
i = 0
while i < 5:
  i += 1
  if i == 3:     #continue the loop
    continue
  print(i)
Output:
1
2
4
5
For Loop
for loop we can execute a set of statements, once for each item in a list, tuple, set etc.
Example:
Alphabets = ["a", "b", "c"]
for x in Alphabets:
  print(x)
Output:
a
b
c

for loop with break Statements
Example:
Alphabets = ["a", "b", "c"]
for x in Alphabets:
  if x == "b":
      break
  print(x)
Output:
a
for loop with continue Statements
Example:
Alphabets = ["a", "b", "c"]
for x in Alphabets:
  if x == "a":
      continue
  print(x)
Output:
b
c

Python Data Types List In Python,  list   is  a  type  of container  in  Data Structures, which  is  used to store multiple data at the same time. Lists  in  Python can be created by just placing the sequence inside the square brackets[].  List  is  mutable   # Creating a List  List  =  []  print ( "Initial blank List: " )  print (List)  # Creating a List with  # the use of a String  List  =  [ 'hello world' ]  print ( " \n List with the use of String: " )  print (List)  # Creating a List with  # the use of multiple values  List...

Python Conditions

Python Conditions and if Statements Equals:  a == b Not Equals:  a != b Less than:  a < b Less than or equal to:  a <= b Greater than:  a > b Greater than or equal to:  a >= b if Statements If is a keyword for conditional statements. Example: a = 33 b = 200 if b > a:   print("b is greater than a") Output: b is greater than a Example: a = 33 b = 200 if b > a: print("b is greater than a") Output: Error *** Indentation Error In case of other programming language, there is a curly brackets, but in python it is different, i.e. white space. Elif statements If the previous statements were not true, try this condition. Example: a = 33 b = 33 if b > a:   print("b is greater than a")   #this condition is not true. elif a == b:   print("a and b are equal") Output:         ...

Basic Operators in Python

Operators   in Python      ·        Arithmetic operators      ·        Relational operators      ·        Logical operators      ·         Bitwise  operators      ·        Assignment   operators      ·        Special operators Arithmetic operators: Arithmetic operators are used to perform mathematical operations like addition, subtraction, multiplication and division. Example: x = 10 y = 4 # Addition of numbers add = x + y # Subtraction of numbers sub = x - y # Multiplication of number mul = x * y # Division(float) of number div1 = x / y # Division(floor) of number div2 = x // y # Modulo of both number mod = x % y # print results print(add) print(sub) pr...
