title: Using folium new version map.save and getting a syntax error
body: <p>I am trying the new version of folium so I am using map.save instead of map.create_map. It was working with the older version but when I am using the new code, I am getting an error again and again saying SyntaxError: Invalid syntax. But I think I ma using the right code:</p>
  
  <p>I am running this script:</p>
  
  <pre><code>import pandas, folium
  
  df = pandas.read_csv(".....txt")
  
  map = folium.Map(location= [df["LAT"].mean(), df["LON"].mean()], zoom_start = 6, tiles = "Stamen Terrain")
  
  def color(elev):
      minimum= int(min(df["ELEV"]))
      step= int((max(df["ELEV"])-min(df["ELEV"]))/3 )
      if elev in range(minimum,minimum+step):
          col= "blue"
      elif elev in range(minimum+step,(minimum+step)*2):
          col= "orange"
      else:
          col = "red"
      return col
  
  
  for lat,lon,name,elev in zip(df['LAT'], df['LON'], df['NAME'], df['ELEV']):
     map.add_child(folium.Marker(location=[lat, lon], popup = name, icon=   folium.Icon(color= color(elev)))       
  
  
  
  map.save(outfile= "test.html")
  </code></pre>
  
  <p>and I am getting this error:</p>
  
  <pre><code>   ...: 
     File "&lt;ipython-input-2-02945dfe5a14&gt;", line 27
       map.save(outfile= "test.html")
         ^
   SyntaxError: invalid syntax
  </code></pre>
  
  <p>Am I doing something wrong?</p>
