Learning Python here: I am simply trying to switch characters in a string. Example: 'A' to 'C'. The string just isn't doing anything. Here is what I have so far:
import string
dummy = "beans"
for i in xrange(len(dummy)):
chr(ord(dummy[i])+5)
print(dummy)
Remember that strings are immutable, so you will need to re-assign your original string. You can try something along these lines:
dummy = "beans"
newdummy = ""
for i in xrange(len(dummy)):
newdummy += chr(ord(dummy[i])+5)
dummy = newdummy
print(dummy)
This would be a more Pythonic approach:
dummy = ''.join(chr(ord(c) + 5) for c in dummy)
print(dummy)
the string.maketrans should be more elegant here:
import string
src = string.ascii_letters
dst = string.ascii_letters[5:] + string.ascii_letters[:5]
trans = string.maketrans(src, dst)
new_dummy = dummy.translate(trans)
for details, please reference the doc of string.maketrans.
Strings in python are immutable. This means that you cannot change them, so you'll have to reassign the variable to a new string instead.
Here's an example:
import string
dummy = "beans"
for i in xrange(len(dummy)):
dummy = dummy[:i] + chr(ord(dummy[i])+5) + dummy[i+1:]
print(dummy)
Or a shorter way:
dummy = "beans"
dummy = "".join([chr(ord(c)+5) for c in dummy])
You can do this by doing:
mystring="hello"
newstring=""
for x in range(len(mystring)):
newstring+=chr(ord(mystring[x])+5)
however, please know that if you do this, and you get up to 251 in the ASCII value, adding 5 will throw an error, so you should check whatever value you are using with an if statement like:
if ord(character)+value<255:
##your ok
else:
##uh oh...
