To create a new page in Magics Python use the page() function, as shown in this example:

Multipage output
#importing Magics module
from Magics.macro import *
 
#Setting of the output file name
output = output(
    output_formats = ['ps'],
    output_name="multipage"
)
 
coast_cream = mcoast(
    map_coastline_land_shade = 'on',
    map_coastline_land_shade_colour = 'cream',
    map_coastline_colour = "tan"
)
 
# create new page
page2 = page()
 
coast_grey = mcoast(
    map_coastline_land_shade_colour =  "grey",
    map_coastline_land_shade = "on",
    map_coastline_colour = "black"
)
 
#Setting the coordinates of the geographical area
scotland = mmap(subpage_map_projection = 'cylindrical',
    subpage_lower_left_latitude= 55.,
    subpage_lower_left_longitude= -9.,
    subpage_upper_right_latitude= 60.,
    subpage_upper_right_longitude=-1.
)
 
# Plot command putting it all together
plot(output, coast_cream, page2, scotland, coast_grey)
