How do I add two numbers and retain their decimal places in the final answer? Below is the code to do this but it does not work.
import re
cnt=0
s=0
l1= []
with open('C://Users/S/Documents/ok5.txt') as f:
for i in f:
if i.startswith('X-DSPAM-Confidence:'):
x = re.findall('\d*?\.\d+',i)
l1.append(x)
cnt+=1
for i in range(0,len(l1)):
j = float(i)
s += j
print(l1)
print(s)
The output I get is:
[['0.5454'], ['0.5677']]
1.0
But, when I try the simple code below it gives the right answer:
a = 0.5454
b = 0.5677
c = float(a+b)
print(c)
The output for this is:
1.1131
I think you want to do this instead:
import re
cnt=0
s=0
l1= []
with open('C://Users/S/Documents/ok5.txt') as f:
for i in f:
if i.startswith('X-DSPAM-Confidence:'):
x = re.findall('\d*?\.\d+',i)
l1.append(x)
s += float(x[0]) # You could just add it here, which improves time complexity
cnt+=1
print(l1)
print(s)
