I am developing and Django website, and I have an array of some str values(parts of url).When user is redirect to:
https://www.example.com/something/name/
how can system system knows that that is part of that arry.
I alredy have this:
urlpatterns = [
path(r'<name1>, views.example')
]
And Array:
arr = [name1,name2,name3, ....namen] # elements of array are assigned to variables in for loop.
Thank you in advance.
So you need to change urlpatterns to:
path('<str:name>,views.example)
str is data type, and other data type for this use are:
int – Matches zero or any positive integer.
str – Matches any non-empty string, excluding the path separator(‘/’).
slug – Matches any slug string, i.e. a string consisting of alphabets, digits, hyphen and under score.
uuid – Matches a UUID(universal unique identifier).
And function call to:
views.example(request, name = "name_n") # for better code reading use name_1, name_2, .. name_n instead of name1,name2 etc.
and that would be it, enjoy in Django.

so i have this code, but when im running it, it's shows that "error : request for member 'nama' in something not a structure or union.
this is an admin program when you buy a movie ticket, and the modul need the name of the admin to print it in the ticket
struct admin
{
char nama[100];
char id[100];
char password[100];
};
struct admin pengatur[100];
ModeAdmin(pengatur[counter]);
void ModeAdmin(struct admin *c)
{
struct admin pembuka;
strcpy(pembuka.nama,c.nama);
strcpy(pembuka.id,c.id);
strcpy(pembuka.password,c.password);
printf("Welcome %s",pembuka.nama);
printf("1. Print Ticket\n");
printf("2. Add New Film\n");
}
This: c.nama should be: c->nama since c is not a struct or union, it's a pointer to a struct.
c is a pointer to a struct, not a struct itself, so you can't use the . operator on it. You need to instead use ->, which dereferences the pointer and then gets the member: strcpy(pembuka.nama,c->nama); strcpy(pembuka.id,c->id); strcpy(pembuka.password,c->password);
Change strcpy(pembuka.nama,c.nama); to strcpy(pembuka.nama,c->nama); And all other occurences of c. likewise. It is necessary because while pembuka is of type struct admin, c is only a pointer to one.

for dateItem in ${times[#]}
do
date2=$(date --date="$dateItem 3 hour ago" +%H:%M:%S)
echo $date2
done
Hi It's worked after doing some changes it works correct, If you wish todo it without an array Here it is: date2=$(date -d "$times 3 hour ago" +"%H:%M:%S") echo $date2
How to get the Query values? [closed]

Improve this question SqlDatasource1 : Table1 ----------- Result_1 ----------- Result_2 I have a query, and I want to get a Result_2 value from the query in code behind, in the BeforePrint event, and I don´t want to put a label in the report, how can I do this? Thanks
If you want to manually run the Select command on your data source, you could try something like (C#):
var dv = new DataView()
dv = Sqldatasource1.Select(DataSourceSelectArguements.Empty) as DataView;
if (dv.Count > 0)
{
foreach (DataRowView rv in dv)
{
string Result2Val = rv["Result_2"].ToString();
// do something with the result...
}
}
I'm sure VB will follow a similar pattern.
Alternatively, try and capture the OnSelected event, if it's already being triggered by another control.

I'm writing a phonebook application and one of the functions is for searching the phonebook by name.
The program should print out the names the same way as the user entered them (later I will include the numbers and other info). The phonebook has 100 contacts.
sname is the name that user have entered to search.
name[a] is name list. Is there any other code like strstr? Like its operating if its found printing them if not then print("not found any") something like this:
for(a=1; a<101; a++) {
while(strstr(name[a],sname) != NULL) {
printf(strstr(name[a], sname));
}
}
You can do that: it is an infinite loop.
while(strstr(name[a],sname)!=NULL){
printf("%s\n",strstr(name[a],sname));
}
None of a, name[a], sname change in the conditions or body of the while
Stop word removal in Javascript [closed]

Improve this question HI I am looking for a library that'll remove stop words from text in Javascript, my end goal is to calculate tf-idf and then convert the given document into vector space, and all of this is Javascript. Can anyone point me to a library that'll help me do that.Just a library to remove the stop words would also be great.
Use the stopwords provided by the NLTK library:
stopwords = ['i','me','my','myself','we','our','ours','ourselves','you','your','yours','yourself','yourselves','he','him','his','himself','she','her','hers','herself','it','its','itself','they','them','their','theirs','themselves','what','which','who','whom','this','that','these','those','am','is','are','was','were','be','been','being','have','has','had','having','do','does','did','doing','a','an','the','and','but','if','or','because','as','until','while','of','at','by','for','with','about','against','between','into','through','during','before','after','above','below','to','from','up','down','in','out','on','off','over','under','again','further','then','once','here','there','when','where','why','how','all','any','both','each','few','more','most','other','some','such','no','nor','not','only','own','same','so','than','too','very','s','t','can','will','just','don','should','now']
Then simply pass your string into the following function:
function remove_stopwords(str) {
res = []
words = str.split(' ')
for(i=0;i<words.length;i++) {
word_clean = words[i].split(".").join("")
if(!stopwords.includes(word_clean)) {
res.push(word_clean)
}
}
return(res.join(' '))
}
Example:
remove_stopwords("I will go to the place where there are things for me.")
Result:
I go place things
Just add any words to your NLTK array that aren't covered already.
I think there are no libraries for such thing, you need to download those words from https://www.ranks.nl/stopwords. And then do replace the words as follows: text = text.replace(stopword, "")
Here's an array with english stopwords. Hope it helps. From http://www.ranks.nl/stopwords (mentioned in previous answer). Also, this could be a helpful resource for you. https://github.com/shiffman/A2Z-F16/tree/gh-pages/week5-analysis http://shiffman.net/a2z/text-analysis/ var stopwords = ["a", "about", "above", "after", "again", "against", "all", "am", "an", "and", "any","are","aren't","as","at","be","because","been","before","being","below","between","both","but","by","can't","cannot","could","couldn't","did","didn't","do","does","doesn't","doing","don't","down","during","each","few","for","from","further","had","hadn't","has","hasn't","have","haven't","having","he","he'd","he'll","he's","her","here","here's","hers","herself","him","himself","his","how","how's","i","i'd","i'll","i'm","i've","if","in","into","is","isn't","it","it's","its","itself","let's","me","more","most","mustn't","my","myself","no","nor","not","of","off","on","once","only","or","other","ought","our","ours","ourselves","out","over","own","same","shan't","she","she'd","she'll","she's","should","shouldn't","so","some","such","than","that","that's","the","their","theirs","them","themselves","then","there","there's","these","they","they'd","they'll","they're","they've","this","those","through","to","too","under","until","up","very","was","wasn't","we","we'd","we'll","we're","we've","were","weren't","what","what's","when","when's","where","where's","which","while","who","who's","whom","why","why's","with","won't","would","wouldn't","you","you'd","you'll","you're","you've","your","yours","yourself","yourselves"];
