How can strings be concatenated?
PythonStringConcatenationPython Problem Overview
How to concatenate strings in python?
For example:
Section = 'C_type'
Concatenate it with Sec_ to form the string:
Sec_C_type
Python Solutions
Solution 1 - Python
The easiest way would be
Section = 'Sec_' + Section
But for efficiency, see: https://waymoot.org/home/python_string/
Solution 2 - Python
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
Solution 3 - Python
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
Solution 4 - Python
More efficient ways of concatenating strings are:
join():
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'
String formatting:
Easy to read and in most cases faster than '+' concatenating
>>> Section = 'C_type'
>>> print 'Sec_%s' % Section
>>> 'Sec_C_type'
Solution 5 - Python
Use + for string concatenation as:
section = 'C_type'
new_section = 'Sec_' + section
Solution 6 - Python
To concatenate strings in python you use the "+" sign
Solution 7 - Python
For cases of appending to end of existing string:
string = "Sec_"
string += "C_type"
print(string)
results in
Sec_C_type
