Instruction:

Write a Python program that reads in the input string and prints out the first character of the first word.

```python

def print_first_word(s):

return s[0]

print(print_first_word("Hello"))

```

The above code will not work as expected because it does not return the first word, but instead it returns the first character of the first word. The problem is due to the fact that the function `print_first_word` is defined as a function that returns the first character of the first word, which means that the function should be defined as a function that takes an input string and returns the first word of the string.

Here is the corrected version of the code:

```python

def print_first_word(s):

words = s.split()

return words[0]

print(print_first_word("Hello"))

```

This corrected version of the code correctly returns the first word of the string.
