Answer:
See explaination
Explanation:
def readFileFirstLast(filename):
# doc string
''' Function accept the filename and opens the fle
and reads all lines and strips new line character and
stores first and last in a string and return that string'''
#eception handle if file not found
try:
#opening the file
f = open(filename)
#reading the first line and striping the ne line
string = f.readline().strip()
#iterating until last line
for line in f:
pass
#concate the last line after strip the new line character to the string
string = string + " " + line.strip()
#return the string
return string
except:
#if file not found
return "File not found"
#taking the file name from user
filename = input("Enter a file name: ")
#printing the doc string in function
print("\ndoc_sting: \n"+ readFileFirstLast.__doc__+"\n")
#printing the returned string by calling the readFileFirstLast()
print("output string :")
print(readFileFirstLast(filename))
Answer:
def print_popcorn_time(bag_ounces):
if bag_ounces<3:
print("Too Small")
elif bag_ounces>10:
print("Too Large")
else:
bag_ounces = bag_ounces*6
print("%s Seconds\n" % bag_ounces)
Explanation:
- Using Python Programming Language
- The function is defined to accept an int parameter
- Within the function body, if...elif and else statements are used to print the desired output
- note the use of the %s placeholder (formated output) and \n for a new line in the final print statement
Only one daemon (server application) can bind to a port. The second one will fail.
No, it is not necessary that variables that contain numbers should always be declared as integer or floating-point data types.
It is not necessary that variables that contain numbers should be declared as integer and floating point data types. Because number can be declared with different data types. As we know that data type is a vital aspect in programming. It describes the type of a value that is contained in a variable. It is the data type based on which memory is allocated to a number or any type of variables.
Numbers can be whole decimal/fractional, signed, unsigned, small, and long. Simply, they exist in a variety of values. According to their values range, the amount of memory is reserved.
Different programming languages offer different data types to store numbers, depending on their types and size. Let’s consider some examples of data types used in programming languages in order to declare variables holding numbers.
- In Python int, float, and complex are the data types used to declare number type variables.
- SQL uses INTEGER, SMALLINT , BIGINT , NUMERIC() , and DECIMAL() data types for numbers.
- To deal with number type variables, Java has six predefined data types, such as int, long, short, byte, float, and double.
- JavaScript uses a single data type called 'number' to declare numbers.
- In C++, two fundamental data types, int and float, are used to represent numeric variables. But C++ is not only limited to these two data types. The data type char can also store numbers. Other data types for declaring numbers as variables are derived from int, float and char, such as short int, long int, signed int, unsigned int, double, long double, signed char, unsigned char etc. etc.
So in concluding remarks, declaring a number type variable is not only limited to using integers and floating-points data types. Rather it entirely depends on the respective programming language, and size and type of the number to be stored in the variable.
