A symbol or set of characters in a programming statement whose value can be changed
Answer:
car_makers = {'Acura':'Japan','Fiat':'Egypt'}
car_makers['Tesla'] = "USA"
car_makers['Fiat'] = "Italy"
print("Acura made in",car_makers['Acura'])
print("Fiat made in",car_makers['Fiat'])
print("Tesla made in",car_makers['Tesla'])
Explanation:
The first line is a define object in the python code, containing two entries of Acura and Fiat and their respective countries.
The python code adds an entry to the object "car maker" using the bracket notation, the tesla car from USA.
The country of the Fiat car is changed from Germany to Italy, using the bracket notation.
The output of the complete object and the individual cars is given.
output of the python code:
{'Acura': 'Japan', 'Fiat': 'Italy', 'Tesla': 'USA'}
Acura made in Japan
Fiat made in Italy
Tesla made in USA.
Answer:
The false statement is "Data maintained in files is often called transient data".
Explanation:
In computer programming, transient data is a temporary storage to hold the value which is created within an application session. The transient data will be discarded at the end of the program. The transient data will be reset to its default value when running the program again. In contrast, file is known as a persistent storage which will still hold data even after end of a program. This is the reason the statement "Data maintained in files is often called transient data" is contradictory and therefore is considered a false statement.
Answer:
Following are the code to this question:
def binarynumber(num):#defining a method binarynumber that accepts a parameter num
x=""#defining a string variable x
if (num!=0):#defining if condition to check number not equal to 0
while (num>=1):#defining a loop that check value is grater then equal to one
if (num %2==0):#defining if condition to check num is even
x=x+"0" #add string value 0 in num variable
num=num/2 #divide the value by 2
else:#defining else block
x=x+"1"#add string value 1 in num variable
num=(num-1)/2#first subtract 1 into num variable then divide the value by 2
else:
x="0"#assign string value 0 in num variable
return "".join(reversed(x))#return value
num = int (input ("Enter any number: "))#defining num variable that input the integer value
print (binarynumber(num))#using print method to call method binarynumber with passing num parameter
Output:
Enter any number: 12
1100
Explanation:
- In the above python code a method "binarynumber" is declared, in which the "num" variable passes as the parameter inside the method a string variable "x" is declared that stores all converted values.
- Inside the method and if the block is declared that checks number value is not equal to 0 if this condition is false then it will add string value and reverse its value.
- Or if the condition is true it defines a while loop that calculates the given number binary digits and returns its value.
- At the last step, the num variable is declared that inputs the integer value from the user end and calls the method by using the print method.
