Python String translate() Method

Example

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

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

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 = str.maketrans(x, y, z)
print(txt.translate(mytable))
