6.5 Write code using find() and string slicing (see section 6.10) to extract the number at the end of the line below. Convert the extracted value to a floating point number and print it out.

py4e_ex_06_05

text = "X-DSPAM-Confidence:    0.8475";

x = text.find(" ")
y = text[x:]
fy=float(y)
print(fy)

text = "X-DSPAM-Confidence: 0.8475";
num=float(text[text.find(':')+1:])
print(num)

check this one easy and simple

text = "X-DSPAM-Confidence: 0.8475";
t = text.find('0.8475')
number = text[t:]
print(float(number))

text = "X-DSPAM-Confidence: 0.8475"
x= text.find(":")
print(x)
y= text[x+1:]
print(y)
value=float(y)
print(value)

My Optimized Solution.

text = "X-DSPAM-Confidence: 0.8475"

Step 1. find 0
Step 2. making a slice of string
Step 3. converting into float
Step 4. printing step

print(float(text[text.find('0'):]))

All solutions were helpful. thanks a bunch...

Very short and precise

y = float(text[text.find(' '):])
print(y)
