Using Python 3.6+ f-string to make a times table
Python f-string is pretty powerful and playful. This project shows how to use f-string to make a times table and then convert it into a Markdown string (but you could actually convert into all kinds of different table string for different purposes, e.g., Latex, RST, CSV, etc.).
The code to make the actual times table is very simple. You would get a zip object from it.
def times_table(int_start=1, int_end=9):
'''
Using Python 3.6+ f-string to make a times table.
Parameters
-----------
int_start : int
The start of the times table.
Default = 1.
int_end : int
The end of the times table.
Default = 9.
Returns
--------
zip : zip object
The times table as a zip object.
'''
int_end = int_end + 1
list_tbl = [
[f'{x} × {y} = {x * y}' for y in range(int_start, int_end)]
for x in range(int_start, int_end)
]
return zip(*list_tbl)With the zip object, you can then use pytablewriter to convert it into
a Markdown string. Note that, on Windows, the code with pytablewriter
needs to be guarded, i.e., you need to put them into the if __name__ == '__main__' block.
if __name__ == '__main__':
int_start = 1
int_end = 9
# make a times table from 1 to 9
list_tbl = list(times_table(int_start, int_end))
list_header = list(range(int_start, int_end + 1))
# use pytablewriter to make a markdown table
writer = pytablewriter.MarkdownTableWriter()
writer.headers = list_header
writer.value_matrix = list_tbl
# copy table string to clipboard
pyperclip.copy(writer.dumps())
writer.write_table()Then, you would get the following times table.
Times table from 1 to 9

The string you get is the following.

You can easily get the string in other formats. All you need to do is
change the writer from Markdown to the desired one. See the documentation
of pytablewriter for more details.
Here is an example for reStructuredText.
writer = pytablewriter.RstGridTableWriter().. table::
