Q5. What is namespace in Python?
Ans: A namespace is a naming structure used to ensure that names are one of a kind to ignore naming conflicts.
Q6. What is PYTHONPATH?
Ans: It is a domain variable that is used when a module is imported. At whatever point a module is imported, PYTHONPATH is ensured to check for the nearness of the imported modules in different catalogs. The medium utilizes it to figure out which module to stack.
Q7. What are python modules?
Ans: Python modules are documents containing Python code. This code can either be capacity classes or factors. A Python module is a .py record containing executable code.
Q8. What are nearby factors and global factors in Python?
Worldwide factors:
Factors pronounced outside a capacity or in global space are called global factors.
Nearby factors:
Any factor announced inside capacity is known as a nearby factor. This variable is available in the neighborhood space and not on a global scale.
Model:
- a=2
- def add ()
- b=3
- c=a+b
- print(c)
- add ()
Output =5
At the point when you attempt to get to the nearby factor outside the capacity add(), it will show an error.
Q9. Is python case sensitive?
Ans: Yes. Python is a sensitive language.
Q10. What is type conversion in Python?
Ans: Type conversion refers to the change of one information type into another.
int() – changes over any information type into number sort
skim() – changes over any information type into drift type.
ord() – changes over characters into the whole number
hex() – changes over whole numbers to hexadecimal
oct() – changes over the whole number to octal
tuple() – This capacity is to change over to a tuple.
set() – This capacity restores the sort in the track of changing over to set.
list() – This capacity is to change over any information type to a rundown sort.
dict() – This capacity is to change over a tuple of application (key, value) into a word reference.
str() – Used to change the over number into a string.
complex(real,imag) – This function converts genuine numbers to complex(real,imag) numbers.
Q11. How to introduce Python on Windows and set way factor?
Ans: To introduce Python on Windows, follow the beneath steps:
- Introduce python from this connection: https://www.python.org/downloads/
- After this, introduce it to your PC. Search for the area where PYTHON has started on your PC utilizing the accompanying order on your order brief: cmd python.
- In that case, go to making edge structure settings and include another variable and name it as PYTHON_NAME and paste the copy one.
- Search for the way factor, select its worth, and select EDIT
- Add a semicolon towards the end of the value if it is not present and then type %PYTHON_HOME%

Q12. Is the space required in python?
Ans: Section is vital for Python. It indicates a square of code. All code inside circles, classes, capacities, and so forth this shows inside a sectioned square. This utilized four space characters. On the off chance that your code is not ordered, it will not perform precisely and will cast mistakes also.
Q13. What is the difference between Python Arrays and lists?
Ans: Arrays and lists, in Python, have a similar method of putting away information. Be that as it may, groups can hold just a single information type component though records can hold any data type components.
Q14. What is lambda's work?
Ans: An unknown capacity is known as a lambda work. This capacity can have any number of boundaries at the same time, can have only one line.
Q15. What is self in Python?
Ans: Self is an example of an object of a class. In Python, this is the first parameter In any case, it is not the situation in Java where it is your choice. It assists with separating between the techniques and qualities of a place with nearby factors.
Q16. What is the contrast between range and xrange?
Ans: range() and xrange() are two functions that could be used to iterate a definite number of times in for loops in Python. For the most part, xrange and range are precisely the same as far as usefulness. The two of them give an approach to produce a rundown of numbers for you to utilize.
It implies xrange does not produce a static rundown at run-time as the range does. It makes the qualities as you need them with an extraordinary procedure called yielding. This method is utilized with a kind of item known as generators. That implies that on the off chance that you have a big range you would prefer to produce a list for, state one billion, xrange is the capacity to utilize.
