Harshit is doing great job . He is amazing and extraordinary.I am a big fan of his.
Little shorter code would be:
def num_to_str(t):
return [str(i) for i in t if type(i) in (int, float)]

how we print the integer list inside the list[1, 2, 3]

[abhisarikasingh]

You have given the input here urself after writing the function.
But Suppose I want to take inputs from user ( user can give any type of input including int, float, char, list, etc).Then how can we write the code for this exercise?

[newdreamza-z]

can you suggest a way if user input is required in that case i think each input type will be of string type

[behindthescene]

Brother we didn't declared any empty list for storing...so where does it storing ....is it storing in the same list ?

[zybi]

[nct-nocopyrightthumbnail]

Sir please reply me if user input is required how to do it will too complicated for me

[shamimsarker]

def func(ara):
ara2 = [str(i) for i in ara if (type(i) == float or type(i) == int)]
return ara2
ara = [1, 2, True, False, 1.0, [1, 2, 3], {4, 5, 6}]
Numbers = []
Numbers = func(ara)
print(Numbers)
#LoveFromBangladesh

[jstinsane]

Is wrote if type(i) is int . I did not gave ==. The correct output is coming but is it right??

[apna-bolly-tolly-wood]

list_ = [[True, False], ['1', '2', '3'], [1, 2.0, 3]]
list2_ = [i for i in list_ for j in i if type(j) == int or type(j) == float]
print(list2_)

[avilashbhowmik]

*_Sir your source code doesn't exist and the dropbox page is showing error like Error (404)._*

[behindthescene]

Is it necessary to check the type of data

[razzakahmad]

sir ji why didn't u use tuple and dictionary in list ? i am stuck at it i actually managed to get list"s element in the form of complete tuple but how can i access the data of tuple in a list??? this answer was ordinary.

[DeepakSharma-milo]

sir, but print(type(string_func(['name', 'false', [1, 2, 3], 1, 1.0, 2]))) output: <class:'list'> de rha hai na ki <class :'str'>

[vedjain]

Sir i have a question
Boolean value ke baad ka list [1, 2, 3] kyu output mai nhi aaya only 1, 1.0, 3 hi aaya float aaya thik hai 1, 3 no bhi but list mai no. hai then why this value not shown in output

[ARGamingMusicVlog]

Good Morning!! Sir!! Why there is no '2' in the output. After all, 2 is also a number that should be changed to string?

[privateStream]

Sir Please Help Me Out !!!


Problem :-


Mene kuch dino se try kar raha hu ki jab bhi me list bana tha hu input function aur split method use karke aur phir me uss me int value input kar tha hu toh woh string me hota hai. aur jab me usse int()
function use kar ke int me change kar tha hu toh muje error ata hai.



Practically Occurring Problem :-


Numbers = input(" Enter Any Number : ").split(", ") # for eg i have input 1, 2, 3, 4


# Lists Would Be display as Numbers = ['1', '2', '3', '4']


# When i try To Change It in integer



Numbers = int(Numbers)
print(Numbers)


Output :-

Error!! Occurs !!!



Please Help To solve this doubt !!!!

Number_List1 = [True, False, [1, 2, 4], 1, 1.0, 3]
def
return [str(Each_Element) for Each_Element in Number_List1 if type(Each_Element) is int or type(Each_Element) is float]

[Maneesh]
