Python Try, Except, Else, Finally

🐍 When an error is reported by Python, you certainly don't want the code to stop abruptly. You would want some actions to be taken if an error is reported. For this, 'Try' is used in Python.

'Try' executes a code. 'Except' captures errors and carries out actions when a certain or any error is reported in the lines executed by Try. 'Else' is optional and follows Except. Lines in Else is executed if no errors are reported. 'Finally' comes at the end and is optional too. Lines in Finally are executed irrespective of errors found or not.

Example:

#Runs on Jupyter Notebook
while True:
    try:
        result = int(input("Provide an integer:"))
    except:
        print("That is not an integer.")
        continue
    else:
        print(f"The integer you entered is {result}")
        break
    finally:
        print("Let's do it again.")

'Continue' and 'Break' comes to use when a while loop is used. Since we wanted to repeat the task again and again until an integer is input by user, we have used 'While' loop. Break is used to end while loop abruptly. Continue is used to inform our program to go on without stopping.

Two Ways of rendering in React Examples

Two Ways of rendering in React Examples 1 - Render twice HTML < div id = "p1" ></ div > < div id = "p2" ></ div > CSS . person { display : inline - block ; margin : 10px ; border : 1px solid # eee ; box - shadow : 0 2px 2px # ccc ; } JAVASCRIPT (Babel) function Person ( props ) { return ( < div className = ' person "> < h1 >{ props . name }</ h1 > < p > Age :{ props . age }</ p > </ div > ); } ReactDOM . render (< Person name = "VK" age = "29" />, document . querySselector ( '#p1' )); ReactDOM . render (< Person name = "HK" age = "28" />, document . querySselector ( '#p2' )); 2 Render all at once HTML < div id = "app" ></ div > CSS . person { display : inline - block ; margin : 1...

Python - Mathematical Functions - Hexadecimal, Binary, Exponential, Absolute, Round

🐍 Some mathematical functions are in-built in python. Here are some of them. Convert Decimal to Hexadecimal hex(246) Output: '0xf6' hex(512) Output: '0x200' 0x is prefix to all hexadecimal numbers in output. The number after 0x is the hexadecimal value. Convert Decimal to Binary bin(1234) Output: '0b10011010010' bin(246) Output: '0b11110110' bin(512) Output: '0b1000000000' Exponential Function pow() function is similar to num1**num2, but it comes useful when you want to execute (num1**num2)%num3. Passing three arguments to pow(), does this. pow(3,4) Output: 81 This works just like 3**4 pow(3,4,5) Output: 1 But this, works equivalent to (3**4)%5. Either of the two ways can be used. At this point I feel (3**4)%5 is better, as anybody reading the code will understand what is being done immediately. While with pow(2,3,4), the person may have to refer to documentation to understand how this function works. Absolute Value The function abs() is used ...

Difference between .exec() and .execPopulate() in Mongoose?

Here I answer what is the difference between .exec() and .execPopulate() in Mongoose? .exec() is used with a query while .execPopulate() is used with a document Syntax for .exec() is as follows: Model.query() . populate ( 'field' ) . exec () // returns promise . then ( function ( document ) { console . log ( document ); }); Syntax for .execPopulate() is as follows: fetchedDocument . populate ( 'field' ) . execPopulate () // returns promise . then ( function ( document ) { console . log ( document ); }); When working with individual document use .execPopulate(), for model query use .exec(). Both returns a promise. One can do without .exec() or .execPopulate() but then has to pass a callback in populate.
