t = 1000

salaries=list(map(lambda x,y:x-y,salaries,t ))
print(salaries)

Answer 1

Make an iterable and fill it with subtracting value.

salaries = [ 2000, 1800, 3100, 4400, 1500 ]
t = tuple( 1000 for i in range( len( salaries ) ) )
salaries = list( map( lambda x, y: x - y, salaries, t ) )
print( salaries )
