You may also need to use float(s) to convert a string or number to a floating point number or combination of both as follows:
int(s)
float(s)
int(float(s))
Examples
x = '123456'
Confirm the object type:
type(x)
Sample outputs:
<type 'str'>
Convert a string to an int and store it to i, run:
i = int(x) type(i)
Sample outputs:
<type 'int'>
However, the following string to int will fail:
x='123456.334' y=int(x)
Sample outputs:
ValueError Traceback (most recent call last) /home/vivek/ in () ValueError: invalid literal for int() with base 10: '123456.334'
Try the following solution:
x='123456.334' y=int(float(x)) type(x) type(y) print y a='12.5' b='13.5' print( int(float(a))+ int(float(b)) )
Finally, you can also use floating point class for decimal arithmetic:
x='123.34' import decimal i=int(Decimal(x)) print(i) type(i)

Hey, I get an error output when I input i=int(Decimal(x)), NameError: name ‘Decimal’ is not defined. Forgive me, I’m new to Python. Can you explain this?
I DONT REALLY KNOW BUT I CAN FIND OUT FOR YOU AND ANYWAY THTS THE EXACT SAME THING IM STUCK ON
Hi, try to write your Decimal like this (decimal):
x=’123.34′
import decimal
i=int(decimal.Decimal(x))
print(i)
type(i)

thnx:)!
import array i=0 verts = list(xrange(1000)) f = open("gluon.txt", "r+") words = f.read().split() for w in words: verts[i]=int('w') i += 1Im getting the error:
Traceback (most recent call last): File "C:\Anil\Python\test.py", line 7, in verts[i]=int('w') ValueError: invalid literal for int() with base 10: 'w'Please help me
thanks
Good. But how do you convert the string ‘5.3.5’ to float number?
how can i turn a sentence that a user has input into numbers
