Given the following python statement…

avg_str = 'Average value read: 0.72903'

Use the find() method and string slicing

to extract the potion of the string after

the colon character and then use the float()

function to convert the extracted string

into a floating point value. Save your code

in a file named “parse_float.py”.

"""

avg_str = 'Average value read: 0.72903'

start_pos = avg_str.find(':');

# 1 more since start_po is after :

start_pos = start_pos + 1;

# taking the number portion of the string

number_portion = avg_str[start_pos:];

# typecasting number_portion to float

number_portion = float(number_portion)
