python check if string is float code example

Example 1: check if string can be converted to int python

# CHECKING IF INT
variable='3'
try:
    int(variable)
    # this will execute if it is integer
    print('You typed an int')
except ValueError:
  	# otherwise this will execute
    print('You did not type an int')

# CHECKING IF FLOAT
variable='3'
try:
    float(variable)
    print('You typed a float')
except ValueError:
    print('You did not type a float')

Example 2: python is float

def is_number(x):
    '''
        Takes a word and checks if Number (Integer or Float).
    '''
    try:
        # only integers and float converts safely
        num = float(x)
        return True
    except ValueError as e: # not convertable to float
        return False

Example 3: check if float is integer python

>>> def isFloatInteger(float):
>>> 	return float.is_integer()
>>> isFloatInteger(0.62)
False
>>> isFloatInteger(1.00)
True

Example 4: py test if is float

check_float = isinstance(25.9, float)

Example 5: check if a string is float python

try:
    float(element)
except ValueError:
    print "Not a float"
