Syntax:



float(x)

The method only accepts one parameter and that is also optional to use. If no argument is passed then the method returns 0.0.

Example 1:

Python3




string= "3.141"
  
print(string)
print(type(string))
  
# converting string to float
Float = float(string)  
  
print(Float)
print(type(Float))

Output:

3.141
<type 'str'>
3.141
<type 'float'>

Example 2:

Python3




string = '55.567'
  
float = float(string)
  
print(type(float))
print('Float Value =', float)

Output:

<type 'float'>
('Float Value =', 55.567)
