Check a float value contains a minus sign (hyphen-minus) - Python
I just want to check the variable contains a negative value but it keeps throwing me this error:
Traceback (most recent call last):
File "C:.........file.py", line 88, in <module>
main()
File "C:.........file.py", line 33, in main
if '-' in done:
TypeError: argument of type 'float' is not iterable
[Finished in 0.2s with exit code 1]
I have looked at others with similiar error but none of them gave me the idea to my current problem.
Still new to python and programming not having a good grasp on this.
Hopefully you can guide me in the right way.
Appreciate your help, folks!
I have done this so far:
def main():
val = '-96000'
flo = float(val)
if '-' in flo:
print('yes')
if __name__ == '__main__':
main()
python

You already have a floating point value. Check it before converting or just useif flo < 0:.

String characters don't exist in float objects. Just perform a numeric comparison:
if flo < 0:
print('yes')
The keyword in is used to iterate an iterable object such as a str instance, so your logic would work with a string:
if '-' in val:
print('yes')
Of course, in the second instance it's wiser to compare against the first character or the start of the string, e.g. val[0] == '-' or val.startswith('-').

Simply remove the cast from str to float, so you can control the minus sign is present:
def main():
val = '-96000'
if '-' in val:
print('yes')
if __name__ == '__main__':
main()
Or better, control that the str actually begins with the minus sign:
if val.startswith('-'):
print('yes')
Or better, still cast to float, then control the value of your data:
def main():
val = '-96000'
flo = float(val)
if flo < 0:
print('yes')
if __name__ == '__main__':
main()
