I think this should be relatively simple, but I can't figure it out. I have a string that represents coordinates, +27.5916+086.5640 and I need to put a comma in between the longitude and latitude so I get +27.5916,+086.5640.
I'm looking through the API but I can't seem to find something for this.
Oh and I have to use Python 2.7.3 since the program I writing for doesn't support Python 3.X.

Use concatenation to insert a character into a string at an index. To insert a character into a string at index i , split the string using the slicing syntax a_string[:i] and a_string[i:] . Between these two portions of the original string, use the concatenation operator + to insert the desired character.
1. Using String. Insert a character at the beginning of the String using the + operator. Insert a character at the end of the String using the + operator.
The % symbol in Python is called the Modulo Operator. It returns the remainder of dividing the left hand operand by right hand operand.
To insert characters that are illegal in a string, use an escape character. An escape character is a backslash \ followed by the character you want to insert.
If your coordinates are c, then this would work. Note, however, this will not work for negative values. Do you have to deal with negatives as well?
",+".join(c.rsplit("+", 1))
For dealing with negatives as well.
import re
parts = re.split("([\+\-])", c)
parts.insert(3, ',')
print "".join(parts[1:])
OUTPUT
+27.5916,+086.5640'
And for negatives:
>>> c = "+27.5916-086.5640"
>>> parts = re.split("([\+\-])", c)
>>> parts.insert(3, ',')
>>> "".join(parts[1:])
'+27.5916,-086.5640'
