Help me record the code with one line using the roster generator.

[shizuka]

Tell me how this code is:

production_year_x, production_year_y = 2014, 2015
rus_name_x, rus_name_y = 'Terminator 1', 'Terminator 2'
if production_year_x is not None:

main_x = rus_name_x + ' | ' + str(production_year_x)

else:

main_x = rus_name_x + ' | '
if production_year_y is not None:

compare_y = {site_y: rus_name_y + ' | ' + str(production_year_y)}

else:

compare_y = {site_y: rus_name_y + ' | '}

Do you want me to write one line through the list generator?

I've been able to write this code, but I can't drive it crazy.

main_x, compare_y,a,b = [name + ' | ' + str(year) for name in [rus_name_x, rus_name_y] for year in [production_year_x, production_year_y]]

In this case, the result is:

1. main_x = 'Terminator 1 ' 2014'
2. compare_y = 'Terminator 2 ' 2015'

I've got the lists on the individual variables because if I don't, the list generator very long.

production_year_x, production_year_y = 2014, 2015
rus_name_x, rus_name_y = 'Terminator 1', 'Terminator 2'    
#
names = [rus_name_x, rus_name_y]
years = [production_year_x, production_year_y]
main_x, compare_y = [names[years.index(year)] + ' | ' + str(year) if year is not None else names[years.index(year)] + ' | ' for year in years]
print(main_x, '\n', compare_y)
Terminator 1 | 2014
Terminator 2 | 2015
production_year_x, production_year_y = 2014, None

Terminator 1 | 2014

Terminator 2 |

production_year_x, production_year_y = None, 2015

Terminator 1 |

Terminator 2 | 2015

production_year_x, production_year_y = None, None

Terminator 1 |

Terminator 2 |

The traditional type of generator:

for name in [rus_name_x, rus_name_y]:

i = [rus_name_x, rus_name_y].index(name)

year = [production_year_x, production_year_y][i]

if year is not None:

x = name + '|' + str(year)

else:

x = name + '|'

print(x)
