How to concatenate strings in python?
Section = 'C_type'
Concatenate it with
Sec_ to form the string:
The easiest way would be
Section = 'Sec_' + Section
But for efficiency, see: https://waymoot.org/home/python_string/
To concatenate strings in python you use the “+” sign
+ for string concatenation as:
section = 'C_type' new_section = 'Sec_' + section
you can also do this:
section = "C_type" new_section = "Sec_%s" % section
This allows you not only append, but also insert wherever in the string:
section = "C_type" new_section = "Sec_%s_blah" % section
More efficient ways of concatenating strings are:
Very efficent, but a bit hard to read.
>>> Section = 'C_type' >>> new_str = ''.join(['Sec_', Section]) # inserting a list of strings >>> print new_str >>> 'Sec_C_type'
Easy to read and in most cases faster than ‘+’ concatenating
>>> Section = 'C_type' >>> print 'Sec_%s' % Section >>> 'Sec_C_type'
Just a comment, as someone may find it useful – you can concatenate more than one string in one go:
>>> a='rabbit' >>> b='fox' >>> print '%s and %s' %(a,b) rabbit and fox
For cases of appending to end of existing string:
string = "Sec_" string += "C_type" print(string)
