You can use char in “aeiouAEIOU” to determine if a character is a vowel, and use a list comprehension to produce a list containing only vowels, and find the number of vowels in the input string by finding the length of this list. string=raw_input() numOfVowels=len([char for char in string if char in “aeiouAEIOU”]) print(numOfVowels) Input: … Read more
Check this code. string=”2017-01-20T21:55:00Z” print string[0:10] Output: 2017-01-20 string=”2017-01-20T21:55:00Z” print string[11:19] Output: 21:55:00 2 solved How to split date and time from a string in Python 3?
There are a few errors in your program. Firstly, you declare your function parameter without setting the data type of the parameter. Generally, declaring a function has the following format: return_type function_name(input_type input_parameter, …) { // Do whatever you want } In the above, the input type refers to the data type of the variable … Read more
I found some issues with your code, just simple stuff that every beginner goes through (I did), I’ll bullet them off: MyTitle isn’t myTitle, JavaScript variables are case-sensetive. You should stay away from the onclick attribute; he’s a bad influence. The point, inline JS is generally not a good idea. So I added an event … Read more
I don’t know what you’re trying to accomplish but your code has a few logical bugs. Perhaps you intended to do s1.substr(i, 4) instead of s1.substr(i, i+4). The second argument of substr is length. Even after doing this you might enter infinite loop because the length of the string is increasing by 1 every-time you … Read more
GridView1.DataSource = Sabt; GridView1.DataBind(); Sabt seems to be single object. To bind DataGrid you need to have collection like List<JadvalSabtenam > or BindingList<JadvalSabtenam> Try that: List<JadvalSabtenam > dataSource = new List<JadvalSabtenam> {Sabt}; GridView1.DataSource = dataSource; GridView1.DataBind(); Reason for that is: What Grid should do with single object? When it’s collection each item is corresponding to … Read more
Yeah it’s a bit of a ridiculous use of linq to be honest, given that strings can be enumerated/indexed directly there isn’t any need to use linq to effectively turn them into a “char plus index the char is at” tuple.. The linqy bit would look like: int index = 0; foreach (var digit in … Read more
If your a double loop that solves this problem breaks out of the loops as soon as a match is found, then both methods are similarly inefficient – they both require iterating over all of N elements M times, worst-case, where N is the length of one array and M is the length of the … Read more

If that is the exact solution that you want. Following code snippet may help you. const arr = [ { type: ‘type’, fields: [‘field1’]}, { type: ‘type2’}, { type: ‘type’, fields: [‘field2’]} ] const modifyArr = (data) => { let res = []; arr.map((item) => { if(item.type == data.type){ if(Object.keys(item).includes(‘fields’)){ res = res.concat(item.fields); } } … Read more
There are several problems with your code: go and run is not a valid parameter declaration in the function header. There is confusion here with the parameter and the string value that you expect the function to be called with. In the function header you should list the parameter(s) with variable names. Since the function … Read more
If you have an array declared like int a[N]; where N is some positive integer value then the valid range of indices to access elements of the array is [0, N). It means that for example this for loop for(i=1;i<=10;i++) { printf(“enter 10 nos. for arr[%d] :”,i); scanf(“%d”,&arr[i]); } must look like for ( i … Read more
Just reindent your code you will find strange { like the one after printf(“Positive”); Juste removing this strange { and fixing your coding style will be: #include<stdio.h> int main() { int x; scanf(“%d”, &x); if ( x > 0 ) { printf(“Positive”); if ( x % 2 == 0 ) { printf(“Even”); } else { … Read more
A typical fast solution to the gcd algorithm would be some iterative version like this one: def gcd(x, y): while y != 0: (x, y) = (y, x % y) return x In fact, in python you’d just use directly the gcd function provided by fractions module. And if you wanted such function to deal … Read more
Probably, you want to pass the arguments from the command line as follows: php /path/to/www/path/to/script.php arg1 arg2 In PHP script, you can access the variables as follows. <?php // $argv[0] is ‘/path/to/wwwpublic/path/to/script.php’ $argument1 = $argv[1]; $argument2 = $argv[2]; ?> Please let me know your thoughts. 1 solved how ca I get variable from ubuntu and … Read more
