Python - Intersection of two String

PythonServer Side ProgrammingProgramming

In this article, we are going to learn how to intersect two strings in different ways.

Follow the below the steps to solve the problem.

  • Initialize two strings and an empty string.
  • Iterate over the first string and add the current character to the new string if it presents in the second string as well and not present in new string already.
  • Print the result.

Example

 Live Demo

# initializing the string
string_1 = 'tutorialspoint'
string_2 = 'tut'

result = ''

# finding the common chars from both strings
for char in string_1:
   if char in string_2 and not char in result:
      result += char

# printing the result
print(result)

If you run the above code, then you will get the following result.

Output

tu

We'll use the set to intersect two strings. Follow the below steps.

  • Convert two strings into sets.
  • Intersect two sets using intersection method.
  • Convert the result to string using join method.
  • Print the result.

Example

 Live Demo

# initializing the string
string_1 = 'tutorialspoint'
string_2 = 'tut'

# intersection
result = set(string_1).intersection(string_2)

# converting to string
result_str = ''.join(result)

# printing the result
print(result_str)

If you run the above code, then you will get the following result.

Output

ut
