Module stringold

Common string manipulations.

Public module variables:

whitespace -- a string containing all characters considered whitespace lowercase -- a string containing all characters considered lowercase letters uppercase -- a string containing all characters considered uppercase letters letters -- a string containing all characters considered letters digits -- a string containing all characters considered decimal digits hexdigits -- a string containing all characters considered hexadecimal digits octdigits -- a string containing all characters considered octal digits

string

expandtabs(s, tabsize=...)

string

ljust(s, width)
Return a left-justified version of s, in a field of the specified width, padded with spaces as needed.

int

index(s, sub, start=... , end=...)
Like find but raises ValueError when the substring is not found.

int

rindex(s, sub, start=... , end=...)
Like rfind but raises ValueError when the substring is not found.

find(s, sub, start=... , end=...)
Return the lowest index in s where substring sub is found, such that sub is contained within s[start,end].

list of strings

splitfields(str, sep=... , maxsplit=...)
Return a list of the words in the string s, using sep as the delimiter string.

list of strings

split(str, sep=... , maxsplit=...)
Return a list of the words in the string s, using sep as the delimiter string.

string

rstrip(s)
Return a copy of the string s with trailing whitespace removed.

string

translate(s, table, deletechars=...)
Return a copy of the string s, where all characters occurring in the optional argument deletechars are removed, and the remaining characters have been mapped through the given translation table, which must be a string of length 256.

int

count(s, sub, start=..., end=...)
Return the number of occurrences of substring sub in string s[start:end].

string

joinfields(list, sep=...)
Return a string composed of the words in list, with intervening occurrences of sep.

string

rjust(s, width)
Return a right-justified version of s, in a field of the specified width, padded with spaces as needed.

string

lower(s)
Return a copy of the string s converted to lowercase.

string

swapcase(s)
Return a copy of the string s with upper case characters converted to lowercase and vice versa.

int

atoi(s, base=...)
Return the integer represented by the string s in the given base, which defaults to 10.

long

atol(s, base=...)
Return the long integer represented by the string s in the given base, which defaults to 10.

float

atof(s)
Return the floating point number represented by the string s.

string

join(list, sep=...)
Return a string composed of the words in list, with intervening occurrences of sep.

string

center(s, width)
Return a center version of s, in a field of the specified width.

int

rfind(s, sub, start=... , end=...)
Return the highest index in s where substring sub is found, such that sub is contained within s[start,end].

string

zfill(x, width)
Pad a numeric string x with zeros on the left, to fill a field of the specified width.

replace(s, old, new, maxsplit=0)

replace (str, old, new[, maxsplit]) -> string

Return a copy of string str with all occurrences of substring old replaced by new. If the optional argument maxsplit is given, only the first maxsplit occurrences are replaced.

capwords(s, sep=None)

capwords(s, [sep]) -> string

Split the argument into words using split, capitalize each word using capitalize, and join the capitalized words using join. Note that this replaces runs of whitespace characters by a single space.

ljust(s, width)

Return a left-justified version of s, in a field of the specified width, padded with spaces as needed. The string is never truncated.

Returns: string

find(s, sub, start=... , end=...)

Return the lowest index in s where substring sub is found, such that sub is contained within s[start,end]. Optional arguments start and end are interpreted as in slice notation.

Return -1 on failure.

Returns: in

splitfields(str, sep=... , maxsplit=...)

Return a list of the words in the string s, using sep as the delimiter string. If maxsplit is nonzero, splits into at most maxsplit words If sep is not specified, any whitespace string is a separator. Maxsplit defaults to 0.

(split and splitfields are synonymous)

Returns: list of strings

split(str, sep=... , maxsplit=...)

(split and splitfields are synonymous)

Returns: list of strings

count(s, sub, start=..., end=...)

Return the number of occurrences of substring sub in string s[start:end]. Optional arguments start and end are interpreted as in slice notation.

Returns: int

joinfields(list, sep=...)

Return a string composed of the words in list, with intervening occurrences of sep. The default separator is a single space.

(joinfields and join are synonymous)

Returns: string

rjust(s, width)

Return a right-justified version of s, in a field of the specified width, padded with spaces as needed. The string is never truncated.

Returns: string

atoi(s, base=...)

Return the integer represented by the string s in the given base, which defaults to 10. The string s must consist of one or more digits, possibly preceded by a sign. If base is 0, it is chosen from the leading characters of s, 0 for octal, 0x or 0X for hexadecimal. If base is 16, a preceding 0x or 0X is accepted.

Returns: int

atol(s, base=...)

Return the long integer represented by the string s in the given base, which defaults to 10. The string s must consist of one or more digits, possibly preceded by a sign. If base is 0, it is chosen from the leading characters of s, 0 for octal, 0x or 0X for hexadecimal. If base is 16, a preceding 0x or 0X is accepted. A trailing L or l is not accepted, unless base is 0.

Returns: long

join(list, sep=...)

Return a string composed of the words in list, with intervening occurrences of sep. The default separator is a single space.

(joinfields and join are synonymous)

Returns: string

center(s, width)

Return a center version of s, in a field of the specified width. padded with spaces as needed. The string is never truncated.

Returns: string

rfind(s, sub, start=... , end=...)

Return the highest index in s where substring sub is found, such that sub is contained within s[start,end]. Optional arguments start and end are interpreted as in slice notation.

Return -1 on failure.

Returns: int

zfill(x, width)

Pad a numeric string x with zeros on the left, to fill a field of the specified width. The string x is never truncated.

Returns: string
