.replace

Question

Guys if i have a code like this:

Txt= "abcdabcd"
New_txt= txt.replace("a", "1")
Print (new_txt)

Its possible to replace, for example, a and b in the same .replace line? Or i have do make a new line to change b?

Answer 1

An other approach for multiple replacement is using maketrans and translate:

# sample with translate
intab = "aeiou"
outtab = "12345"
trstab = str.maketrans(intab, outtab)

str = "this is ground control to major Tom"
print(str)
print(str.translate(trstab))
# output: th3s 3s gr45nd c4ntr4l t4 m1j4r T4m

# ----------
trans = str.maketrans('ae', 'bx') # a->b and e->x
strText = 'abcdef'
print(strText.translate(trans))
# output: bbcdxf

you can also try this:
use a dict with all the replacing pairs:

table ={'a':'1', 'b':'2'}

txt= "abcdabcd"
print('original string: ',txt) # only for demo
for i in table:
txt = txt.replace(i,table.get(i))
print('final string: ',txt) # only for demo
