python - How can I search a string for multiple characters? -

i trying extract info page lot of spaces in it, pretty want search letter , position, not 1 letter. how can accomplished?

edit: want search website http://www.aviationweather.gov/static/adds/metars/stations.txt user inputted city, anchorage. program search anchorage. want grab next 4 letters, way txt formatted number of spaces between city , 4 letter code different each town.

you can use

listed = text.split() 

to separate text on whitespaces. have list consisting of characters.

citypos = listed.index("anchorage") code = listed[citypos+1][:4] 

to search letters , numbers do:

positions = [] y = 0 x in text:     if x.isalnum(): positions.append(y)     y += 1 

that looked before edited question.
