Answer:
The program to this question as follows:
Program:
def lettersOnly(s): #defining method lettersOnly
val="" #defining string variable that return value
for i in s: #defining loop to calculate value
if(i.isalpha()): #check condition that value is string
val=val+ i #add value
return val #return value
print(lettersOnly("data3base_ro1c3k5s")) #call method and print value
Output:
databaserocks
Explanation:
In the above python code, a method lettersOnly is declared that accepts a string variable "s" in its parameter. Inside the method, a string variable "val", and loop is declared, in which the "val" variable holds method return value.
- In the loop and if block is used that uses "isalpha" string method, which checks the check alphabetic character in the given value. if this is true it will calculate all value in "val" variable and return its value.
- At the last, the print method is used, which calls the lettersOnly method and prints its return value.
A search stagey is useful because you can make complicated searches easily and also get reliable data.
Answer:
The answer is "Option b"
Explanation:
In the given code three-class C1, C2, and C3 are declared, in which C2 and C3 extend the class C1. In the next line, C2 and C3 object are created, that is c2 and c3. and in the last line c2 class object holds two-class C2, C1, and one object c3 value, this code will give runtime error because it can't cast object from sibling class, and wrong choices can be defined as follows:
- In option a, It is not correct because it can't cast c3 object into c2 object.
- In option c, It is not correct because it performs multiple casting in nested forms.
- In option d, It is wrong because the statement is not correct.
Answer:
The following code is written in java programming language:
//set if statement
if (((modelYear >= 1999) && (modelYear <= 2002) && (modelName == "Extravagant")) || ((modelYear >= 2004) && (modelYear <= 2007) && (modelName == "Guzzler")))
{
recalled = true; //initialized Boolean value
}
else //set else statement
{
recalled = false; ////initialized Boolean value
}
Explanation:
Here, we set the if statement and set condition, if the value of modelYear is greater than equal to 1999 and less that equal to 2002 and modelName is equal to "Extravagant" or the value of modelYear is greater than equal to 2004 and less than equal to 2007 and the model year is equal to "Guzzler", than "recalled" initialized to "true".
Otherwise "recalled" initialized to "true".
