# ModuleNotFoundError: What does it mean main is not a package?

I am trying to run a module from the console. The structure of my directory is this:

I am trying to run the module `p_03_using_bisection_search.py`

, from the `problem_set_02`

directory using:

```
$ python3 p_03_using_bisection_search.py
```

The code inside `p_03_using_bisection_search.py`

is:

```
__author__ = 'm'
"""
Docstring
"""
from .p_02_paying_debt_off_in_a_year import compute_balance_after
def compute_bounds(balance: float,
annual_interest_rate: float) -> (float, float):
""""
Docstring
"""
# there is code here, but I have omitted it to save space
pass
def compute_lowest_payment(balance: float,
annual_interest_rate: float) -> float:
"""
Docstring
"""
# there is code here, but I have omitted it to save space
pass
def main():
balance = eval(input('Enter the initial balance: '))
annual_interest_rate = eval(input('Enter the annual interest rate: '))
lowest_payment = compute_lowest_payment(balance, annual_interest_rate)
print('Lowest Payment: ' + str(lowest_payment))
if __name__ == '__main__':
main()
```

I am importing a function that is in `p_02_paying_debt_off_in_a_year.py`

which code is:

```
__author__ = 'm'
"""
Docstring
"""
def compute_balance(balance: float,
fixed_payment: float,
annual_interest_rate: float) -> float:
"""
Docstring
"""
# this is code that has been omitted
pass
def compute_balance_after(balance: float,
fixed_payment: float,
annual_interest_rate: float,
months: int=12) -> float:
"""
Docstring
"""
# Omitted code
pass
def compute_fixed_monthly_payment(balance: float,
annual_interest_rate: float) -> float:
"""
Docstring
"""
# omitted code
pass
def main():
balance = eval(input('Enter the initial balance: '))
annual_interest_rate = eval(
input('Enter the annual interest rate as a decimal: '))
lowest_payment = compute_fixed_monthly_payment(balance,
annual_interest_rate)
print('Lowest Payment: ' + str(lowest_payment))
if __name__ == '__main__':
main()
```

I am getting the following error:

```
ModuleNotFoundError: No module named '__main__.p_02_paying_debt_off_in_a_year'; '__main__' is not a package
```

I have no idea how to solve this issue. I have tried adding a `__init__.py`

file, but it is still not working.

Simply remove the dot for the relative import and do:

```
from p_02_paying_debt_off_in_a_year import compute_balance_after
```
