Using Python Permutations function on a String

permutation of a string in python

# Function to find permutations of a given string

     # Get all permutations of string 'ABC'
     permList = permutations(str)
  
     # print all permutations
     for perm in list(permList):
         print (''.join(perm))
        
# Driver program

find all permutations of a string

void permute(string a, int l, int r)  
{  
    // Base case  
    if (l == r)  
        cout<<a<<endl;  
    else
    {  
        // Permutations made  
        for (int i = l; i <= r; i++)  
        {  
  
            // Swapping done  
            swap(a[l], a[i]);  
  
            // Recursion called  
            permute(a, l+1, r);  
  
            //backtrack  
            swap(a[l], a[i]);  
        }  
    }  
}  

get all permutations of string

# get all permutations of string
import itertools
for p in itertools.permutations('123'):
    print(p)					# ( ' 1 ', ' 2 ', ' 3 ') ( ' 1 ' , ' 3 ', ' 2 ' ) ( ' 2 ', ' 1 ', ' 3 ' )

how to print all permutations of a string

void permutation(string s)
{
    sort(s.begin(),s.end());
	do{
		cout << s << " ";
	}
    while(next_permutation(s.begin(),s.end()); // std::next_permutation
    
    cout << endl;
}
