Given a text file, transpose its content.

You may assume that each row has the same number of columns, and each field is separated by the ' ' character.

Example:

If file.txt has the following content:

name age
alice 21
ryan 30

Output the following:

name alice ryan
age 21 30

```
python3 <<EOF
matrix = [line[:-1].split(' ') for line in open('file.txt')]
for column in range(len(matrix[0])):
    print(*(matrix[row][column] for row in range(len(matrix))))
EOF
```
