Python program to print all odd numbers in a range

Given starting and endpoints, write a Python program to print all odd numbers in that given range. 

Example:

Input: start = 4, end = 15
Output: 5, 7, 9, 11, 13, 15

Input: start = 3, end = 11
Output: 3, 5, 7, 9, 11

Example #1: Print all odd numbers from the given list using for loop 

1. Define the start and end limit of the range.
2. Iterate from start till the range in the list using for loop and 
3. check if num % 2 != 0. 
4. If the condition satisfies, then only print the number. 

Python3

# Python program to print odd Numbers in given range

start, end = 4, 19

# iterating each number in list
for num in range(start, end + 1):

    # checking condition
    if num % 2 != 0:
        print(num, end = " ")

Output:

5 7 9 11 13 15 17 19 

Example #2: Taking range limit from user input 

Python3

# Python program to print Even Numbers in given range

start = int(input("Enter the start of range:"))
end = int(input("Enter the end of range:"))

# iterating each number in list
for num in range(start, end + 1):

    # checking condition
    if num % 2 != 0:
        print(num)

Output:

Enter the start of range: 3
Enter the end of range: 7
3
5
7

Example #3: Taking range limit from user input or with static inputs to reduce code execution time and to increase code performance.

Python3

# Uncomment the below two lines for taking the User Inputs
#start = int(input("Enter the start of range: "))
#end = int(input("Enter the end of range: "))

# Range declaration
start = 5
end = 20

if start % 2 != 0:

    for num in range(start, end + 1, 2):
        print(num, end=" ")
else:

    for num in range(start+1, end + 1, 2):
        print(num, end=" ")

Output

5 7 9 11 13 15 17 19 

Example #4: Taking range limit from user input 

Python3

# Python program to print Even Numbers in given range

start = int(input("Enter the start of range: "))
end = int(input("Enter the end of range: "))

#create a list that contains only Even numbers in given range
even_list = range(start, end + 1)[start%2::2]

for num in even_list:
    print(num, end = " ")

Enter the start of range: 3
Enter the end of range: 11
3 5 7 9 11 

Method: Using the lambda function

Python3

# Python code To print all odd numbers
# in a given range using the lambda function
a=3;b=11
li=[]
for i in range(a,b+1):
    li.append(i)
# printing odd numbers using the lambda function
odd_num = list(filter(lambda x: (x%2!=0),li))
print(odd_num)

Output

[3, 5, 7, 9, 11]

Method: Using recursion 

Python3

def odd(num1,num2):
    if num1>num2:
        return
    print(num1+1,end=" ")
    return odd(num1+2,num2)
num1=4;num2=15
odd(num1,num2)

Output

5 7 9 11 13 15 

Method: Using list comprehension

Python3

x = [i for i in range(4,15+1) if i%2!=0]
print(*x)

Output

5 7 9 11 13 15

Method: Using the enumerate function 

Python3

a=4;b=15;l=[]
for i in range(a,b+1):
  l.append(i)
print([a for j,a in enumerate(l) if a%2!=0])

Output

[5, 7, 9, 11, 13, 15]

Method: Using pass 

Python3

a=4;b=15
for i in range(a,b+1):
  if i%2==0:
    pass
  else:
    print(i,end=" ")

Output

5 7 9 11 13 15 

Method: Using filter method:

Python3

# Python program to print Even Numbers in given range

# Range declaration
a=4;
b=15;

#create a list that contains only Even numbers in given range
l= filter(lambda a : a%2 , range(a, b+1))
print(*l)

Output:

5 7 9 11 13 15
