How to convert the UTM to Lat/Long in Python?

Question

{
  "type": "MultiPolygon",
  "coordinates": [[[
        [6707794.77817316, 1952512.97762237],
        [6707794.43138905, 1952566.21209599],
        [6707897.49942442, 1952567.26754007],
        [6707897.9039513, 1952513.5347079],
        [6707794.77817316, 1952512.97762237]
      ]]]
}

these are my UTM coordinates for Sacramento city

from pyproj import Proj
Lat = 52.063098675
Lon = -114.132980348
ZoneNo = "11" #Manually input or from other sources
myProj = Proj("+proj=utm +zone="+\
ZoneNo+", +north +ellps=WGS84 +datum=WGS84 +units=m +no_defs")
Lon2, Lat2 = myProj(UTMx, UTMy,inverse=True)



 [57.645243963689346, -97.82662155895939][57.64521883657446, 
-97.82633467103226][57.64520287229081, -97.82615238782866] 
[57.64518564728056, -97.82595574421379][57.646086991794625, 
-97.82587777819731][57.64614690939316, -97.8265560026529] 
[57.645243963689346, -97.82662155895939]

But this return coordinates located at Canada. But I want to Locate this longitudinal and latitudinal's in SACRAMENTO city

Can anyone help me to convert the correct format to convert the UTM to LAN LONG coordinates.

your coords are halfway between calgary and edmonton - in canada: https://www.google.de/maps/place/52%C2%B003'47.2%22N+114%C2%B007'58.7%22W/@52.6329169,-121.8445565,5z/data=!4m5!3m4!1s0x0:0x0!8m2!3d52.0630987!4d-114.1329803 — Patrick Artner, Jun 09 '18 at 11:58

Your coordinates are using the "NAD83(NSRS2007) / California zone 2 (ftUS)" coordinate system:

from django.contrib.gis.geos import Polygon
from pprint import pprint

DATA = [
    [6707794.77817316, 1952512.97762237],
    [6707794.43138905, 1952566.21209599],
    [6707897.49942442, 1952567.26754007],
    [6707897.9039513, 1952513.5347079],
    [6707794.77817316, 1952512.97762237]
]

poly_california = Polygon(DATA, srid=3492)
poly_gps = poly_california.transform(4326, clone=True)
pprint(poly_gps.coords)

Result:

(((-121.48923204074042, 38.52249222070792),
  (-121.48923220705949, 38.5226384001039),
  (-121.48887193496923, 38.52263970700418),
  (-121.48887157735834, 38.522492158296565),
  (-121.48923204074042, 38.52249222070792)),)

(Tip: GeoJSON should only use WGS84)
