I am new to python. I am trying to read each line from a file and then for each line, I have to first read a string and then a series of floats. How can I do this using python-2.7? An example of the text file:
phon_R01_S01_1 119.99200 157.30200 74.99700
phon_R01_S01_2 122.40000 148.65000 113.81900
phon_R01_S01_3 116.68200 131.11100 111.55500
I can read float numbers from file. I am currently reading each line from file but after that I am failing to extract/save/print both string and float numbers from line separately.
Edit1: For clarification to @zipa: I have tried below part to extract floats:
import numpy as np
from pprint import pprint
li = []
for line in open("a.txt"):
nums = line.split() # split the line into a list of strings by whitespace
nums = map(float, nums) # turn each string into a float
pprint(nums)
#li.extend(nums)
print line
pprint(li)
I haven't done any part to extract string. I couldn't find any. Above code gives this obvious below error.
nums = map(float, nums) # turn each string into a float
ValueError: could not convert string to float: phon_R01_S01_1
