Python maketrans method – Before moving ahead, let’s know a little bit about Python translate() method
Introduction – It creates or returns a mapping table that can be used with translate() method to replace specified characters.
Syntax – String.maketrans(x, y, z) Parameter Values - x – It is required value. If one parameter is specified then it has to be dictionary to describe how to replace a specified character. If two or more parameter is specified then it has to be string that specifying the character to be replaced. y – It is an optional value. Its parameter should be same as parameter x. Each character in parameter x will be replaced with this parameter. z - It is an optional value. A string describes which character has to be removed from original string.
Example 1 – Replaced a specified letter ‘H’ with ‘J’
txt = "Hello Python!"
mydict = txt.maketrans('H' , 'J')
print(txt.translate(mydict))
Example 2 – Use of mapping table with third parameter to remove original characters from string.
w = "Hello Python World!"
x = 'Heoll'
y = 'Jeoll'
trans= w.maketrans(x , y)
print("Translated string:" , w.translate(trans))
Example 3 – Use of mapping table with third parameter to remove original characters from string.
w = "Hello Python World!"
x = 'Hello'
y = 'Jello'
z = 'l'
trans= w.maketrans(x , y , z) # translate string
print("Translated string:" , w.translate(trans))
Example 4 – The method maketrans() itself returns a dictionary to describe each replacement, in unicode:
w = "Hello Python World!"
x = 'Hello' #
y = 'Jello'
z = 'l'
print('Translated String:' , w.maketrans(x , y , z))
