Python making infinite range and list

Question

How we can make an infinite range or list and put numbers from zero or -inf to +inf ?

Answer 1

mojaka ,

since it is not clearly defind what the input range or output should be, it would be very helpful if you do an attempt and link it here.

> do you need to get one or more random values out of a range of values?

> do you need to get sequential values in a defined range?

Answer 2

mojaka ,

(1) the code you presented is working! an other way would be to use the string method .isdigit():

... loop with variable `c`
if c.isdigit():
...

doing so, we can avoid the try... except... code block.

(2) i did not get your last question, can you explain what you need? what is the core task of your exercise?

Answer 3

I'm pretty sure it would lead to time-out....

Answer 4

But an infinite list has no end, so your program would forever be compiling to create the list. You could make a very large list, I'm not sure what limit there is (I'm sure the information is online 😉).

Here are some codes with lists in python. See what you can learn from them.

Answer 5

Loop the string and check if the character is a number.

for c in string:
try:
int(c)
print("string has a number")
except:
continue
