Last Updated :

Given a String. The task is to find out the Number Of Words And Characters Present In The String.
Examples:
Input: Geeksforgeeks is best Computer Science Portal
Output:
The number Of Words are : 6
The Number Of Characters are : 45
Input: Hello World!!!
Output:
The original string is : Hello World!!!
The number of words in string are : 2
The number of words in string are : 14
Count The Number Of Characters present in a string using len() function. You can also use a for loop for counting characters
char=0
for i in string:
char=char+1
For Counting
Method 1: Using split()
The split function is quite useful and usually quite a generic method to get words out of the list, but this approach fails once we introduce special characters in the list.
Python3
test_string = "Geeksforgeeks is best Computer Science Portal"
print ( "The original string is : " + test_string)
res = len (test_string.split())
print ( "The number of words in string are : " + str (res))
print ( "The number of words in string are : " , len (test_string))
|
Output:
The original string is : Geeksforgeeks is best Computer Science Portal
The number of words in string are : 6
The number of words in string are : 45
Method 2: Using regex module
Here findall() function is used to count the number of words in the sentence available in a regex module.
Python3
import re
test_string = "GeeksForGeeks is a learning platform"
print ( "The original string is : " + test_string)
res = len (re.findall(r '\w+' , test_string))
print ( "The number of words in string are : " + str (res))
print ( "The number of Characters in string are : " , len (test_string))
|
Output:
The original string is : GeeksForGeeks is a learning platform
The number of words in string are : 5
The number of Characters in string are : 36
Time Complexity: O(n)
Auxiliary Space: O(n)
Method 3: Using sum()+ strip()+ split() function
Here we first check all the words in the given sentence and add them using the sum() function.
Python3
import string
test_string = "GeeksForGeeks is a learning platform"
print ( "The original string is: " + test_string)
res = sum ([i.strip(string.punctuation).isalpha() for i in
test_string.split()])
print ( "The number of words in string are : " + str (res))
print ( "The number of characters in string are : " , len (test_string))
|
Output:
The original string is: GeeksForGeeks is a learning platform
The number of words in string are : 5
The number of characters in string are : 36
Method #4 : Using count() and len() methods
Python3
test_string = "Geeksforgeeks is best Computer Science Portal"
print ( "The original string is : " + test_string)
res = test_string.count( " " ) + 1
print ( "The number of words in string are : " + str (res))
print ( "The number of words in string are : " , len (test_string))
|
Output
The original string is : Geeksforgeeks is best Computer Science Portal
The number of words in string are : 6
The number of words in string are : 45
The Time and Space Complexity for all the methods are the same:
Time Complexity: O(n)
Auxiliary Space: O(n)
