# Find combinations without changing order

## Question:

I am trying to generate permutations from this list without changing the order.

```
mylist = [["a", "b"], ["c", "d"], ["e", "f"], ["g", "h"], ["i"]]
```

The expected result:

```
acegi
bcehi
acfgi
bcfhi
adegi
bdehi
adfgi
bdfhi
acegi
bcehi
acfgi
bcfhi
adegi
bdehi
adfgi
bdfhi
```

This code is working as expected. But I will like to know if there is any other way.

```
for f in range(2):
for s in range(2):
for t in range(2):
for f in range(2):
print(
mylist[0][f]
+ mylist[1][s]
+ mylist[2][t]
+ mylist[3][f]
+ mylist[4][0]
)
```

## Answers:

You can use `itertools.product`

:

```
import itertools
mylist = [["a", "b"], ["c", "d"], ["e", "f"], ["g", "h"], ["i"]]
for p in itertools.product(*mylist):
print(''.join(p))
# acegi
# acehi
# acfgi
# acfhi
# adegi
# adehi
# adfgi
# adfhi
# bcegi
# bcehi
# bcfgi
# bcfhi
# bdegi
# bdehi
# bdfgi
# bdfhi
```
