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 −
