如何在python逗号后分割或获取python中的字符串

Question

How would you split a string for every comma it pass it For example, let say I want to grab only the BigCity etc

s="1234 Somestreet Road, BigCity, SomeProvince, A1B 1C1"

so, city = s.split? How would i do it?

Answer 1

I would do something like this:

x=s.split(',')

if len(x)>1:
    x=x[1:] # since you are only concerned with what comes after a ','
    print x[0].strip() # remove the strip(), depends on the usage
else:
    print ''

s="1234 Somestreet Road" => empty string

s="1234 Somestreet Road," => empty string

s="1234 Somestreet Road, BigCity, SomeProvince, A1B 1C1" => BigCity

Answer 2

In [247]: s="1234 Somestreet Road, BigCity, SomeProvince, A1B 1C1"

In [248]: s.split(',')
Out[248]: ['1234 Somestreet Road', ' BigCity', ' SomeProvince', ' A1B 1C1']

In [249]: s.split(',')[1]
Out[249]: ' BigCity'
