Ans. Difference between.
randint randrange

a random number from the inclusive range. stop, step) doesn’t include the stop number while generating random
integer, i.e., it is exclusive.
This function takes two parameters. Both are mandatory. The This function takes three parameters(start,stop,step). Out of three
randint (start, stop) includes both start and stop numbers while parameters, two parameters are optional. i.e., start and step are the
generating random integer. optional parameters. The default value of start is 0, if not specified.
The default value of the step is 1, if not specified.
For example, random.randint(0, 100) will return any random random.randrange(0, 100) will return any random number between

Output : Global Variable

74. What do you understand by local and global scope Inside add() : 12
of variables? How can you access a global variable In main: 15
inside the function, if function has a variable with Note: In case you have a local variable with the same
same name. [SP 2019-20] name, use the globals() function to access global
variable.
Ans. A global variable is a variable that is accessible globals()[‘your_global_var’]
globally. A local variable is one that is only accessible for ex:
to the current scope, such as temporary variables
y=globals()[‘a’]
used in a single function definition.
A variable declared outside of the function or in 76. Give the output
global scope is known as global variable. def fun():
This means, global variable can be accessed inside print(a)
or outside of the function where as local variable can a=5
be used only inside of the function. We can access fun()
by declaring variable as global A. print(a)
75. Explain the use of global key word used in a function Ans. 5
with the help of a suitable example. [SP 21] 5
Ans. Use of global key word: In Python, global keyword 77. Give the output
allows the programmer to modify the variable outside
the current scope. It is used to create a global variable
def fun():
and make changes to the variable in local context. a=10
A variable declared inside a function is by default print(a)
local and a variable declared outside the function a=5
is global by default. The keyword global is written fun()
inside the function to use its global value. Outside print(a)
the function, global keyword has no effect. Ans. 10
Example: 5
c = 10 # global variable
78. Give the output
def add():
def fun():
global c
global a
c = c + 2
a=10
# global value of c is incremented
print(a)
by 2
a=5
print(“Inside add():”, c)
fun()
add()
print(a)
c=15
print(“In main:”, c)
Ans. 10
output: 10
