By default, uploaded files are limited to 200MB. You can configure this using the `server.maxUploadSize` config option. For more info on how to set config options, see https://docs.streamlit.io/library/advanced-features/configuration#set-configuration-options Parameters ---------- label : str A short label explaining to the user what this file uploader is for. The label can optionally contain Markdown and supports the following elements: Bold, Italics, Strikethroughs, Inline Code, Emojis, and Links. This also supports: * Emoji shortcodes, such as ``:+1:`` and ``:sunglasses:``. For a list of all supported codes, see https://share.streamlit.io/streamlit/emoji-shortcodes. * LaTeX expressions, by wrapping them in "$" or "$$" (the "$$" must be on their own lines). Supported LaTeX functions are listed at https://katex.org/docs/supported.html. * Colored text, using the syntax ``:color[text to be colored]``, where ``color`` needs to be replaced with any of the following supported colors: blue, green, orange, red, violet, gray/grey, rainbow. Unsupported elements are unwrapped so only their children (text contents) render. Display unsupported elements as literal characters by backslash-escaping them. E.g. ``1\. Not an ordered list``. For accessibility reasons, you should never set an empty label (label="") but hide it with label_visibility if needed. In the future, we may disallow empty labels by raising an exception. type : str or list of str or None Array of allowed extensions. ['png', 'jpg'] The default is None, which means all extensions are allowed. accept_multiple_files : bool If True, allows the user to upload multiple files at the same time, in which case the return value will be a list of files. Default: False key : str or int An optional string or integer to use as the unique key for the widget. If this is omitted, a key will be generated for the widget based on its content. Multiple widgets of the same type may not share the same key. help : str A tooltip that gets displayed next to the file uploader. on_change : callable An optional callback invoked when this file_uploader's value changes. args : tuple An optional tuple of args to pass to the callback. kwargs : dict An optional dict of kwargs to pass to the callback. disabled : bool An optional boolean, which disables the file uploader if set to True. The default is False. This argument can only be supplied by keyword. label_visibility : "visible", "hidden", or "collapsed" The visibility of the label. If "hidden", the label doesn't show but there is still empty space for it above the widget (equivalent to label=""). If "collapsed", both the label and the space are removed. Default is "visible". Returns ------- None or UploadedFile or list of UploadedFile - If accept_multiple_files is False, returns either None or an UploadedFile object. - If accept_multiple_files is True, returns a list with the uploaded files as UploadedFile objects. If no files were uploaded, returns an empty list. The UploadedFile class is a subclass of BytesIO, and therefore it is "file-like". This means you can pass them anywhere where a file is expected. Examples -------- Insert a file uploader that accepts a single file at a time: >>> import streamlit as st >>> import pandas as pd >>> from io import StringIO >>> >>> uploaded_file = st.file_uploader("Choose a file") >>> if uploaded_file is not None: ... # To read file as bytes: ... bytes_data = uploaded_file.getvalue() ... st.write(bytes_data) >>> ... # To convert to a string based IO: ... stringio = StringIO(uploaded_file.getvalue().decode("utf-8")) ... st.write(stringio) >>> ... # To read file as string: ... string_data = stringio.read() ... st.write(string_data) >>> ... # Can be used wherever a "file-like" object is accepted: ... dataframe = pd.read_csv(uploaded_file) ... st.write(dataframe) Insert a file uploader that accepts multiple files at a time: >>> import streamlit as st >>> >>> uploaded_files = st.file_uploader("Choose a CSV file", accept_multiple_files=True) >>> for uploaded_file in uploaded_files: ... bytes_data = uploaded_file.read() ... st.write("filename:", uploaded_file.name) ... st.write(bytes_data) .. output:: https://doc-file-uploader.streamlit.app/ height: 375px ) rerfrCrgrhrirjrkrcrdr:)r_file_uploader) rGrerfrCrgrhrirjrkrcrdr:s r,rnzFileUploaderMixin.file_uploadersN\!"""""7-#   r.)rdrcr:r:c  Pt|}t|j|td|dt || t d||||||t |j| r| jnd } |rwt|tr|g}d|D}d|D}tD]?\} }| |vr||vr| |||vr| |vr| | @t}| |_ ||_||ng|jdd<t!jd|_||_t |j|_| |_t-| |j_|t3||_t7|}t9d||||||j|j|  }|jd|t|jt@rdSt|jtBrd |jDS|jS) NF) default_valuergwrites_allowedrn)user_keyrerfrCrgrhform_idpagec4g|]}|ddkr|nd|S)r.r&)r* file_types r,r-z4FileUploaderMixin._file_uploader..s@'q\S00 o)oor.c6g|]}|Sr&)lower)r*ts r,r-z4FileUploaderMixin._file_uploader..s ,,,!AGGII,,,r.zserver.maxUploadSize)ryon_change_handlerrjrk deserializer serializerr:c<g|]}t|t|Sr&)rOrr)s r,r-z4FileUploaderMixin._file_uploader..s'TTT!A{9S9STATTTr.)"r!rdgrr rr page_script_hashrOr^ TYPE_PAIRSr9FileUploaderProtoidrerfr get_optionmax_upload_size_mbmultiple_filesrzrcrrdvaluerrhrBrrJrX_enqueuerrP)rGrerfrCrgrhrirjrkrdrcr:rxyfile_uploader_protoserde widget_states r,ruz FileUploaderMixin._file_uploader{sSkkTWi000!#eTTTT"5*:;;;  "7#DG,,),6%%$      #$$$ v!%D -,t,,,D" # #199$KKNNN99$KKNNN/11!#$)!.2.>ddB #171B "2 2 ..C*&5dg&>&>#'/$5U 6 6 ,2  '-d||  $!"788 '  '*     *=>>> l(+ 6 6 U4  *D 1 1 UTT|1TTT T!!r.(streamlit.delta_generator.DeltaGeneratorc"td|S)zGet our DeltaGenerator.r)r )rGs r,rzFileUploaderMixin.dgs>EEEr.)NNNNN)FNNNNN)NFNNNNN)r#r)rYrZr[r r^rrr rrrrrr\rrrrnrrrupropertyrr&r.r,raras "".2%))- ,5    C#,-  't}  c]  sm  N+ z" &  *  $|$ %   X $ 16!".2%))- ,5    C#,-  'u~  c]  sm  N+ z" &  *  ,    X . 15!".2%))-,5     't}  C#,-  c]  sm N+ z" &  *  $|$ %   X $ 1604!".2%))-,5     'u~  C#,-  c]  sm N+ z" &  *  ,    X ^O$$15&+!".2%))-Z ,5Z Z Z Z C#,-Z  $ Z c] Z sm Z N+Z z"Z &Z Z *Z  |T,/5 6Z Z Z %$Z ~15&+!".2%))-^"-6*.^"^"^"^"C#,-^" $ ^" c] ^" sm ^"N+^"z"^"&^"*^"^"& '^" |T,/5 6^"^"^"^"@FFFXFFFr.ra)6 dataclassesrtextwraprtypingrrrrr r typing_extensionsr streamlitr streamlit.elements.formr streamlit.elements.utilsrrrstreamlit.proto.Common_pb2rrNrUploadedFileInfoProto streamlit.proto.FileUploader_pb2rrstreamlit.runtime.metrics_utilrstreamlit.runtime.scriptrunnerrrstreamlit.runtime.staterrrrstreamlit.runtime.state.commonr'streamlit.runtime.uploaded_file_managerrrstreamlit.type_utilrrr r!r_rr@rBrar&r.r,rs"!!!!!BBBBBBBBBBBBBBBB%%%%%%333333 SRRRRRPPPPPPNNNNNN999999OOOOOOOO =<<<<<MMMMMMMMXXXXXXXXXXXX|[( )*  12 % k) *+D !!!!!!! !H\F\F\F\F\F\F\F\F\F\Fr.
