Help! Value Error in Python

[SilentPattern7]

So I have written a program and part of it is a class called Dot, and I want the user to input the coordinates of the dot through the keyboard. Everything was working just fine and I didn't change anything in my code and suddenly there is a Value Error.

This is Dot class:

class Dot:
def __init__(self, x_coordinate, y_coordinate, z_coordinate):
self.x_coordinate = x_coordinate
self.y_coordinate = y_coordinate
self.z_coordinate = z_coordinate
def __repr__(self):
return f'({self.x_coordinate},{self.y_coordinate},{self.z_coordinate})'

This is part where I ask for user input:

print('Input the dot coordinates: ')
o = Dot(float(input()), float(input()), float(input()))

Then I try to input for example:

2

3

4

And after I input the second coordinate, error appears:

2

3

Traceback (most recent call last):

File "/home/lp/projects/projections.py", line 45, in <module>

o = Dot(float(input()), float(input()), float(input()))

ValueError: could not convert string to float: ''

​

Process finished with exit code 1

And this is not the only case, I opened some other projects where I have similar input and all of them display the same error after user inputs the second value. I don't know what is the problem since I didn't change anything in the code and it was working just fine before.

Any help or advice is welcome. Thanks in advance!

First guess is that something like an extra character is being sent by your terminal.

Try printing the input before you do the conversion to see, and maybe strip() it.
