Padding a String with Zeros
Padding zeros to the left of a numeric string can be useful for ensuring a consistent length. There are several methods to achieve this in Python:
Padding Strings:
Use the zfill() method on a string to add leading zeros:
1 2 |
|
Padding Numbers:
For numbers, use the string formatting operator (f-string):
1 2 |
|
Alternatively, use the % operator or the format() function:
1 2 |
|
You can also use dictionary-style formatting:
1 2 |
|
Or, use the placeholder syntax with format strings:
1 |
|
The 03 in the formatting string specifies the desired width of the padded string, and the 0 signifies that it should be padded with zeros.
Refer to the String formatting documentation for more information on all available formatting options.
