      Python Tutorial

      This Python tutorial has been written for the beginners to help them understand the basic to advanced concepts of Python Programming Language. After completing this tutorial, you will find yourself at a great level of expertise in Python, from where you can take yourself to the next levels to become a world class Software Engineer.

      String Exercises

      Example 1

      Python program to find number of vowels in a given string.
      mystr = "All animals are equal. Some are more equal"
      vowels = "aeiou"
      count=0
      for x in mystr:
         if x.lower() in vowels: count+=1
      print ("Number of Vowels:", count)
      It will produce the following output
      Number of Vowels: 18

      Example 2

      Python program to convert a string with binary digits to integer.
      mystr = '10101'
      
      def strtoint(mystr):
         for x in mystr:
            if x not in '01': return "Error. String with non-binary characters"
         num = int(mystr, 2)
         return num
      print ("binary:{} integer: {}".format(mystr,strtoint(mystr)))
      It will produce the following output
      binary:10101 integer: 21
      Change mystr to '10, 101'
      binary:10,101 integer: Error. String with non-binary characters

      Example 3

      Python program to drop all digits from a string.
      digits = [str(x) for x in range(10)]
      mystr = 'He12llo, Py00th55on!'
      chars = []
      for x in mystr:
         if x not in digits:
            chars.append(x)
      newstr = ''.join(chars)
      print (newstr)
      It will produce the following output
      Hello, Python!
