Python String translate() Method

❮ String Methods


Example

Replace any "S" characters with a "P" character:

#use a dictionary with ascii codes to replace 83 (S) with 80 (P):
mydict = {83:  80}
txt = "Hello Sam!"
print(txt.translate(mydict))
Try it Yourself »

Definition and Usage

The translate() method returns a string where some specified characters are replaced with the character described in a dictionary, or in a mapping table.

Use the maketrans() method to create a mapping table.

If a character is not specified in the dictionary/table, the character will not be replaced.

If you use a dictionary, you must use ascii codes instead of characters.


Syntax

string.translate(table)

Parameter Values

Parameter Description
table Required. Either a dictionary, or a mapping table describing how to perform the replace

More Examples

Example

Use a mapping table to replace "S" with "P":

txt = "Hello Sam!"
mytable = txt.maketrans("S", "P")
print(txt.translate(mytable))
Try it Yourself »

Example

Use a mapping table to replace many characters:

txt = "Hi Sam!"
x = "mSa"
y = "eJo"
mytable = txt.maketrans(x, y)
print(txt.translate(mytable))
Try it Yourself »

Example

The third parameter in the mapping table describes characters that you want to remove from the string:

txt = "Good night Sam!"
x = "mSa"
y = "eJo"
z = "odnght"
mytable = txt.maketrans(x, y, z)
print(txt.translate(mytable))
Try it Yourself »

Example

The same example as above, but using a dictionary instead of a mapping table:

txt = "Good night Sam!"
mydict = {109: 101, 83: 74, 97: 111, 111: None, 100: None, 110: None, 103: None, 104: None, 116: None}
print(txt.translate(mydict))
