## Python sets: Exercise-2 with Solution

Write a Python program to iteration over sets.

Sample Solution-1:

Iterate over the set without indexes:

Python Code:

``````#Create a set
num_set = set([0, 1, 2, 3, 4, 5])
for n in num_set:
print(n, end=' ')
print("\n\nCreating a set using string:")
char_set = set("w3resource")
# Iterating using for loop
for val in char_set:
print(val, end=' ')
```
```

Sample Output:

```0 1 2 3 4 5

Creating a set using string:
c e 3 u r o w s
```

Sample Solution-2:

Iterating over a set as indexed list:

Python Code:

``````char_set = set("w3resource")
char_set = list(char_set)
# Iterating over a set as a indexed list
for id in range(len(char_set)):
print(char_set[id], end=' ')
```
```

Sample Output:

```3 w o u e r s c
```

Sample Solution-3:

Using the enumerate type:

Python Code:

``````num_set = {0, 1, 2, 3, 4, 5}
# Iterate over the set
for value,char in enumerate(num_set):
print(char, end=' ')
```
```

Sample Output:

```0 1 2 3 4 5
```

## Python: Tips of the Day

Combining Lists Using Zip:

• Takes multiple collections and returns a new collection.
• The new collection contains items where each item contains one element from each input collection.
• It allows us to transverse multiple collections at the same time.
```name = 'abcdef'
suffix = [1,2,3,4,5,6]
zip(name, suffix)
--> returns (a,1),(b,2),(c,3),(d,4),(e,5),(f,6)
```
