ValueError: invalid literal for int() with base 10: '7.9'
#Convert string to number python 2.7 code#
The rules for converting a Unicode string into the ASCII encoding are simple for each code point: If the code point is < 128, each byte is the same as the value of the code point. For example, Python’s default encoding is the ‘ascii’ encoding. On the other hand, print(int("7.9")) will result in an error since a float as a string object cannot be converted to an integer. Encodings don’t have to handle every possible Unicode character, and most encodings don’t. But it isn’t available in Python 3 or later. However, Python 2.7 also had a function called Unicode() that used to produce Unicode strings. It simply takes a number value and converts it to a string. For example : print(int(7.9)) will print 7. There is another Python standard library function called Str().
import decimal scientificnotation '7.810500161524e+25' decimalnumber decimal. Then (if necessary) you can convert the decimal value to an integer or a string. Output: Traceback (most recent call last): You can convert your string '7.810500161524e+25' to a decimal.Decimal number without altering its precision at all the way you will if you convert it to a floating point value. This is further illustrated in the next example: age = "18"
Example Usage: # Here age is a string objectĪlthough the output is visually similar, keep in mind that the first line is a string object while the following line is an integer object. Similar to the built-in str() method, Python also offers the handy int() method that takes a string object as an argument and returns an integer.
