Online Minúscula Convertidor

Essentially, I am trying to convert a dynamic url in the form of example.com/products/productName/ into a url where the productName is all lowercase. In urls.py, I have

    path('products/<str:productName>/', product_detail_view)

...this should redirect to a product detail page with the productName (whatever that might be) in all lowercase.

I tried appending .lower() to the 'products//' and that turned the field productName into productname which is not a recognized field in models.py.

I then tried 'products//' which also didn't work at all? Anyone have any suggestions?

Here is my problem: I'm building a StringBuilder and I built a toLowerCase() method which only gives me back a single character and not the whole string.

 public MyStringBuilder1 toLowerCase() {      String newStr = "";      for (int i = 0; i < s.length(); i++) {        if (s.charAt(i) >= 'A' && s.charAt(i) <= 'Z') {          newStr = newStr + (char)(s.charAt(i) + 32) + "";        }      }      return new MyStringBuilder1(newStr);    } public static void main(String[] args) {       // Create a MyStringBuilder1 object       MyStringBuilder1 str1 = new MyStringBuilder1("Radixsort");       // Display string as lowercase       System.out.println("\nString to lower case: " + str1.toLowerCase());  }

I want to use the *args to input the name and change the even numbers for the character to Upper Case and odd number character to lower case. For example, Myname -> MyNaMe

I used the following code for the operation. But it is output all the characters as upper case. (If I add any random variable under myfunc1(x), then it is working properly.)

Using *args :

def myfunc1(*args):    result=''    for i in range(0,len(args)):        if i%2==0:            result+=args[i].upper()        else:            result+=args[i].lower()    print(result)myfunc1('My Name') # prints "MY NAME"

Using random Variable:

def myfunc1(my_string):    result=''    for i in range(0,len(my_string)):        if i%2==0:            result+=my_string[i].upper()        else:            result+=my_string[i].lower()    print(result)myfunc1('Myname') # prints MyNaMe

I am currently learning c# with an online tutorial. So far I have been able to solve every exercise but this one I cannot figure it out:

Write a program asking the user a string. Then it will modify the string by changing uneven letters (first, third...) into lowercase and even letters (second, fourth...) into uppercase letters. For instance: "Hello" should look like this --> hElLo.

I am converting the string to uppercase first so I only have to do the lowercase part. In this exercise I am supposed to use StringBuilder but I cannot figure it out. I thought maybe with a for loop I could go through every letter and change those that i%2 != 0 but StringBuilder cannot use ToLower(). I cannot think of a way to change it ToString(), ToLower()and then add it at the end of the string.

Any help will be welcome.

I am wondering that why Character.toUpperCase/toLowerCase has no Locale parameter like String.toUpperCase/toLowerCase.

I have to first uppercase of a text that can be in Any language. I have 2 solutions:

1. Use Character.toUpperCase

   String text = "stack overflow";StringBuilder sb = new StringBuilder(text);   sb.setCharAt(0, Character.toUpperCase(sb.charAt(0))); // No Locale parameter here.String out = sb.toString(); //Out: Stack overflow

2. Use String.toUpperCase

   Locale myLocale = new Locale(locateId);String text = "stack overflow";String text1 = text.substring(0,1).toUpperCase(myLocale );String text2 = text.substring(1);String out = text1 + text2; // Out: Stack overflow

For my Locale. Both way has the same result.

My question is:

• Since the text can be in any language. Which way should I use?

• Why Character.toUpperCase/toLowerCase has no Locale parameter because there is not much difference between Character.toUpperCase/toLowerCase and String.toUpperCase/toLowerCase because String is array of Characters.
