statsmodels.iolib.foreign.savetxt(fname, X, names=None, fmt='%.18e', delimiter=' ')
[source] -
Save an array to a text file.
This is just a copy of numpy.savetxt patched to support structured arrays or a header of names. Does not include py3 support now in savetxt.
Parameters: fname : filename or file handle
If the filename ends in
.gz
, the file is automatically saved in compressed gzip format.loadtxt
understands gzipped files transparently.X : array_like
Data to be saved to a text file.
names : list, optional
If given names will be the column header in the text file. If None and X is a structured or recarray then the names are taken from X.dtype.names.
fmt : str or sequence of strs
A single format (%10.5f), a sequence of formats, or a multi-format string, e.g. ?Iteration %d ? %10.5f?, in which case
delimiter
is ignored.delimiter : str
Character separating columns.

Notes
Further explanation of the
fmt
parameter (%[flag]width[.precision]specifier
):- flags:
-
-
: left justify+
: Forces to preceed result with + or -.0
: Left pad the number with zeros instead of space (see width). - width:
- Minimum number of characters to be printed. The value is not truncated if it has more characters.
- precision:
-
- For integer specifiers (eg.
d,i,o,x
), the minimum number of digits. - For
e, E
andf
specifiers, the number of digits to print after the decimal point. - For
g
andG
, the maximum number of significant digits. - For
s
, the maximum number of characters.
- For integer specifiers (eg.
- specifiers:
-
c
: characterd
ori
: signed decimal integere
orE
: scientific notation withe
orE
.f
: decimal floating pointg,G
: use the shorter ofe,E
orf
o
: signed octals
: string of charactersu
: unsigned decimal integerx,X
: unsigned hexadecimal integer

fmt

>>> savetxt('test.out', x, delimiter=',') # x is an array >>> savetxt('test.out', (x,y,z)) # x,y,z equal sized 1D arrays >>> savetxt('test.out', x, fmt='%1.4e') # use exponential notation
