comment corriger - erreur: mauvaise fuite \ u en position 0

Bonjour, j'essaie d'exporter un html gmap en utilisant ipywidgets dans le cahier jupyter, mais je rencontre l'erreur suivante: - erreur: mauvaise fuite\u à la position 0.

Je suis nouveau dans la programmation et je pourrais utiliser l'aide pour corriger tout ce qui provoque cette erreur. S'il existe un moyen plus simple d'exporter le fichier html, je suis heureux de changer d'approches.

Merci

Voici un extrait du code: je peux ajouter le tout si c'est utile.

import pandas as pd
import gmaps
from ipywidgets.embed import embed_minimal_html
from ipywidgets import IntSlider
gmaps.configure(api_key='XXXX')
pd.options.mode.chained_assignment = None  # default='warn'


file2 = '005 lat:long.csv'
state2 = pd.read_csv(file2)
state2 = state2.rename(columns={'Address1': 'address', 'City':'city', 
                                'State':'state', 'Zip': 'Zip'})

storenumbs = state2['Store'].str.split('#', expand=True)
state2 = state2.join(storenumbs)
state2 = state2.drop(['Store', 0], axis=1)
state2 = state2.rename(columns={1: 'store_#'})
state2['store_#'] = state2['store_#'].astype(int)

fig = gmaps.figure(center=(42.5, -71.4), map_type='TERRAIN', zoom_level=9.8)
scale = 4
one_layer = (gmaps.symbol_layer(low_points_lat_long, fill_color='red', stroke_color='red', scale= scale))
two_layer = (gmaps.symbol_layer(low_med_points_lat_long, fill_color='red', stroke_color='yellow', scale= scale))
three_layer = (gmaps.symbol_layer(med_high_points_lat_long, fill_color='yellow', stroke_color='green', scale= scale))
four_layer = (gmaps.symbol_layer(high_points_lat_long, fill_color='green', stroke_color='green', scale= scale))


fig.add_layer(one_layer)
fig.add_layer(two_layer)
fig.add_layer(three_layer)
fig.add_layer(four_layer)

J'ai eu le même problème pendant

 [m.start() for m in re.finditer('Valuation Date")', 'dummytext')]

*** sre_constants.error: unbalanced parenthesis at position 15

Mais cela a été résolu avec l'aide de re.escape

[m.start() for m in re.finditer(re.escape('Valuation Date")'), 'dummytext')]

Prendre plaisir.
