# string handling

# here are a few string handling possibilities listed: 


# .split(sep)  

# It is used to split a string at the position where the separator sep
# appears. Here the separator sep is ":"   (the one appearing in braces)
# A list is returned. 

txt = "me:you:they"
foo = txt.split(":")  # foo holds now a list that looks like ["me","you","they"]
print foo 


# sep.join(x) 

# It concatenates a sequence of strings x into a single string, with sep added between each item.

txt = ':'.join(["me","you","they"])    # txt holds now a string that looks like "me:you:they"
print txt



# concatenating strings can be done also in the following way

a = "me"
b = "you"
c = "they"
txt = a + b + c   # txt holds now a string that looks like "meyouthey"
print txt
txt_2 = a + ":" + b + ":" + c # txt_2 holds now a string that looks like "me:you:they"
print txt_2



# Converting from integer to a string

a = str(10)   # a holds the string like "10"



# Converting from integer to a unicode string

a = unicode(10)   # a holds the unicode string kind of like u"10"
  


# Converting from string "10" to integer 10

a = int("10")    # a holds the integer 10
