Question

want help in string operation


i want to do like this

temp='faisal' OR temp=['faisal'] OR temp=["faisal"]

now i want to change letter f to something else

how can i do that??

Answer 1

string objects dont support item assignment so you need to do something like this:

temp = "d" + temp[1:]

for the list you could do something like this:

temp[0] = "d" + temp[0][1:]

PS: temp=['faisal'] and temp=["faisal"] are exactly the same thing so you dont need to tell them apart.

Answer 2

what if i want to replace all consonants from a word to "-"

like
faisal

>>>-ai-a-

like this

and i have a list of names like this

name=['faisal,'raza'','life','saver']

and i have to replace all consonants with "-"

Answer 3

what I would do in that situation is first create a list of all the consonants, in the form

listConsonants = [b,c,...]

then I'd create a variable for the new list

rearrangedList = []

then I'd use a loop:

for each word in the wordlist: #to get words
rearrangedWord = '' # empty string so we've got a place to put the word as we're building it
for each letter in word: #iterate over the letters in the word
if the letter isn't in the consonants list: # if the letter is a vowel
add the letter to the rearranged word
if the letter is in the consonants list: # if the letter is a consonant
append the character '-' in place of the letter
add the rearrangedWord to the rearrangedList

Answer 4

thanks bro

now lemme implement this

:)

Answer 5

there are lots of was to implement it. this might work..

names = ["faisal", "brian", "mary"]
newListOfNames = []

def replaceConsonants(name):
consonants = ["b", "c", "d", "f", "g", "h", "j", "k", "l", "m", "n",
"p", "q", "r", "s", "t", "v", "w", "x", "y", "z"]
for consonant in consonants:
newName = name.replace(consonant, "-")
name = newName
return newName

for name in names:
newname = replaceConsonants(name)
newListOfNames.append(newname)

print names
print newListOfNames

test.append(j)
print test

vowels=['a','e','i','o','u']

retest=[]
for i in test:
reword=''
for j in i:
ans=False
for v in vowels:
if j==v:
ans=True
if ans==False:
reword='-'+reword[:]
else:
reword=j+reword[:]
retest.append(reword)

print retest
