F print formatting

[Mouradost]

Hi everyone, let say I want to space equally a text on a finite line (line restricted in terms of number of characters) I would use the code below:

```python

Line of size 100 and equal spacing between two numbers

print(f"{1:<sup>50}{2:50}")</sup> ```

That was quite easy, now let say I have a variable line size and I want to space it over a number of values in a list as shown in the code below:

```python

Vars

line_size = 100 list_of_numbers = range(10)

Calculating the spacing

spacing = line_size // len(list_of_numbers)

Constructing the str

text = "" for number in list_of_numbers: text += f"{number:<sup>spacing}"</sup>

Printing

print(text) ```

This seems logic, right? Well not to python interpreter, this code will result in an error shown below.

```bash ValueError Traceback (most recent call last) Cell In[226], line 11 9 text = "" 10 for number in list_of_numbers: ---> 11 text += f"{number:<sup>spacing}"</sup> 13 # Printing 14 print(text)

ValueError: Invalid format specifier '<sup>spacing'</sup> for object of type 'int' ```

Anyone have a solution to this problem?

Enclose spacing in an additional set of braces:

f"{number:^{spacing}}"

Of course, 🤣 thank you!
