Python Exercise: Check whether a number falls in a given range

Python Functions: Exercise-6 with Solution

Write a Python function to check whether a number falls in a given range.

Sample Solution-1:

Python Code:

def test_range(n):
    if n in range(3,9):
        print( " %s is in the range"%str(n))
    else :
        print("The number is outside the given range.")
test_range(5)

Sample Output:

 5 is in the range

Sample Solution-2:

  • Use arithmetic comparison to check if the given number is in the specified range.
  • If the second parameter, end, is not specified, the range is considered to be from 0 to start.

Python Code:

def test_range(n, start_num, end_num = 0):
  return start_num <= n <= end_num if end_num >= start_num else end_num <= n <= start_num
print(test_range(5, 2, 7))
print(test_range(5, 7))
print(test_range(1, 3, 6))
print(test_range(6, 5))

Sample Output:

True
True
False
False

Python: Tips of the Day

Decapitalizes the first letter of a string:

Example:

def tips_decapitalize(s, upper_rest=False):
  return s[:1].lower() + (s[1:].upper() if upper_rest else s[1:])
print(tips_decapitalize('PythonTips'))
print(tips_decapitalize('PythonTips', True)) 

Output:

pythonTips
