formatting
str.rjust
Returns the string right-justified in a field of the given width, padded on the left with fillchar. Returns the original string unchanged if it is already at least width characters long.
str.rjust(width[, fillchar])Parameters
| Parameter | Purpose |
|---|---|
| width | minimum total width |
| fillchar | single character used to pad (default ' ') |
Examples
>>> '42'.rjust(6)
' 42'padded with spaces on the left
>>> '42'.rjust(6, '0')
'000042'leading zeros — but see zfill for a signed-number-aware variant
>>> 'hello'.rjust(3)
'hello'no truncation when already wide enough
>>> '$'.rjust(5, '.')
'....$'any single fill character
Gotcha
Does not truncate. For signed numbers, use zfill() which keeps the sign in front of the padding.
Related methods
str.center
Returns the string centered in a field of the given width, padded on both sides with fillchar. When padding is uneven, the extra pad placement depends on the parity of width and margin — for the common odd-width case, it lands on the LEFT.
str.zfill
Returns a copy padded on the left with '0' digits to reach the given width. Unlike rjust('0'), it preserves a leading sign ('+' or '-') by placing the zeros after it.
str.format
Substitutes replacement fields delimited by { } in the string with values from args and kwargs, using the Format Specification Mini-Language. In modern Python, f-strings are usually preferred for literals; str.format() remains ideal for templates loaded at runtime.
str.strip
Returns a copy of the string with leading and trailing whitespace removed. If chars is given, removes any leading/trailing characters that appear in the chars set (not a prefix/suffix — it is a character set).
str.lstrip
Returns a copy of the string with leading characters removed. Defaults to whitespace; a chars argument specifies a set of characters to strip from the left.
