How Do I Convert Strings to Numbers (Integers and Floats) in Python?

Converting Strings to Numbers in Python

Python provides convenient methods to convert strings representing numeric values into floating-point (float) or integer (int) types. Here's how you can achieve this:

Converting Strings to Floats

To convert a string containing a decimal value to a float, use the float() function. For example:

a = "545.2222"
float_value = float(a)
print(float_value)  # Output: 545.22220000000004

Converting Strings to Integers

To convert a string representing an integer to an int, use the int() function. Note that this requires the string to contain valid integer digits. For example:

b = "31"
int_value = int(b)
print(int_value)  # Output: 31

Integer to Float Conversion (Optional Step)

In case you need to convert your integer back to a float, you can then use the float() function again:

float_value = float(int_value)

By following these simple steps, you can easily parse strings to obtain numeric values in Python, empowering your code to interact effectively with numerical data.
