I have TXT file with float numbers.
I can not convert it to float array in python.
f = open('Vmat.txt', 'r')
DATA = f.read()
DATA = DATA.split("\n")
for i in range(0,len(DATA),1):
DATA[i] = DATA[i].replace(",","")
DATA[i] = float(DATA[i])
ValueError Traceback (most recent call last)
ipython-input-73-e205bb7634f9 in module
4 for i in range(0,len(DATA),1):
5 DATA[i] = DATA[i].replace(",","")
----> 6 DATA[i] = float(DATA[i])
ValueError: could not convert string to float: ''
The error message states that you are trying to cast an empty string ('') to a float which is impossible. This is probably because you have an empty line at the end of your file.
f = open('Vmat.txt', 'r')
DATA = f.read()
DATA = DATA.split("\n")
for i in range(0,len(DATA),1):
if not DATA[i]:
continue
DATA[i] = DATA[i].replace(",","")
DATA[i] = float(DATA[i])
This might work if the program crashes at the end because of an empty line.
Why are you replacing a comma with nothing? How will it keep its float value and not turn into a integer? DATA[i] = DATA[i].replace(",","") might also help
f = open('Vmat.txt', 'r')
DATA = f.read()
DATA = DATA.split("\n")
NEW_DATA = []
for i in DATA:
try:
if float(i):
NEW_DATA.append(float(i))
except ValueError:
print("Not float value")
print(NEW_DATA)
