How to execute multi-line statements within Python's own debugger (PDB)

由 ◇◆丶佛笑我妖孽 提交于 2019-11-26 18:45:30
问题 So I am running a Python script within which I am calling Python's debugger, PDB by writing: import ipdb; ipdb.set_trace() (iPython's version of PDB, though for the matter I don't think it makes a difference; I use it for the colored output only). Now, when I get to the debugger I want to execute a multi-line statement such as an if clause or a for loop but as soon as I type if condition: and hit the return key, I get the error message *** SyntaxError: invalid syntax (<stdin>, line 1) How can

Specifying maxlength for multiline textbox

由 孤人 提交于 2019-11-26 17:32:44
I'm trying to use asp: <asp:TextBox ID="txtInput" runat="server" TextMode="MultiLine"></asp:TextBox> I want a way to specify the maxlength property, but apparently there's no way possible for a multiline textbox . I've been trying to use some JavaScript for the onkeypress event: onkeypress="return textboxMultilineMaxNumber(this,maxlength)" function textboxMultilineMaxNumber(txt, maxLen) { try { if (txt.value.length > (maxLen - 1)) return false; } catch (e) { } return true; } While working fine the problem with this JavaScript function is that after writing characters it doesn't allow you to

Split large string

由 隐身守侯 提交于 2019-11-26 16:49:47
I have a long text which needs to be converted to small strings so I can include it to an AutoIt script. If I include multi-line text it shows error unterminated string . So I should have: "numbercharswillbe10" &_ "othernumbersofcharwillbe10" &_ etc.. How can I split it with & _ -delimiters? String concatenation As per Documentation - Language Reference - Operators : & Concatenates/joins two strings. &= Concatenation assignment. Example: Global $g_sText = "Long " & "string " & "here." & @CRLF $g_sText &= "More text." & @CRLF ConsoleWrite($g_sText) Multi line statements As per Documentation -

How do I search and replace across multiple lines with Perl?

问题 $ perl --version This is perl, v5.10.1 (*) built for x86_64-linux-gnu-thread-multi $ echo -e "foo\nbar" > baz.txt $ perl -p -e 's/foo\nbar/FOO\nBAR/m' baz.txt foo bar How can I get this replacement to work? 回答1: You can use the -0 switch to change the input separator: perl -0777pe 's/foo\nbar/FOO\nBAR/' baz.txt -0777 sets the separator to undef , -0 alone sets it to \0 which might work for text files not containing the null byte. Note that /m is needless as the regex does not contain ^ nor $

What&#39;s wrong with Groovy multi-line String?

由 假装没事ソ 提交于 2019-11-26 15:43:44
问题 Groovy scripts raises an error: def a = "test" + "test" + "test" Error: No signature of method: java.lang.String.positive() is applicable for argument types: () values: [] While this script works fine: def a = new String( "test" + "test" + "test" ) Why? 回答1: As groovy doesn't have EOL marker (such as ; ) it gets confused if you put the operator on the following line This would work instead: def a = "test" + "test" + "test" as the Groovy parser knows to expect something on the following line

How to get multiline input from user [duplicate]

由 余生长醉 提交于 2019-11-26 15:26:22
This question already has an answer here: How do I read multiple lines of raw input in Python? 7 answers I want to write a program that gets multiple line input and work with it line by line. Why there is no function like raw_input in Python 3? input does not allow user to put lines separated by newline ( Enter ), it prints back only the first line. Can it be stored in variable or even read it to a list? In Python 3.x the raw_input() of Python 2.x has been replaced by input() function. However in both the cases you cannot input multi-line strings, for that purpose you would need to get input

Split code over multiple lines in an R script

由 点点圈 提交于 2019-11-26 15:08:45
问题 I want to split a line in an R script over multiple lines (because it is too long). How do I do that? Specifically, I have a line such as setwd('~/a/very/long/path/here/that/goes/beyond/80/characters/and/then/some/more') Is it possible to split the long path over multiple lines? I tried setwd('~/a/very/long/path/here/that/goes/beyond/80/characters/and/ then/some/more') with return key at the end of the first line; but that does not work. Thanks. 回答1: You are not breaking code over multiple

Best way to split string into lines

由 感情迁移 提交于 2019-11-26 12:19:12
问题 How do you split multi-line string into lines? I know this way var result = input.Split(\"\\n\\r\".ToCharArray(), StringSplitOptions.RemoveEmptyEntries); looks a bit ugly and loses empty lines. Is there a better solution? 回答1: If it looks ugly, just remove the unnecessary ToCharArray call. If you want to split by either \n or \r , you've got two options: Use an array literal – but this will give you empty lines for Windows-style line endings \r\n : var result = text.Split(new [] { '\r', '\n'

What is the proper way to format a multi-line dict in Python?

由 南楼画角 提交于 2019-11-26 11:50:39
问题 In Python, I want to write a multi-line dict in my code. There are a couple of ways one could format it. Here are a few that I could think of: mydict = { \"key1\": 1, \"key2\": 2, \"key3\": 3, } mydict = { \"key1\": 1, \"key2\": 2, \"key3\": 3, } mydict = { \"key1\": 1, \"key2\": 2, \"key3\": 3, } I know that any of the above is syntactically correct, but I assume that there is one preferred indentation and line-break style for Python dicts. What is it? Note: This is not an issue of syntax.
