Conversion of Python Data Types

Conversion of Python Data Types

When we are processing data, some data types are not what we want. What should we do?

1. Data type conversion: type to be converted (data)

• Convert num01 to an integer: int (num01)
• To convert num01 to a floating point: float (num01)
• To convert num01 to a string: str (num01)
• Convert nun01 to boolean: bool (num01)

 

For example:

Print (int ("12345") + 1)

Print (float ("12.345") + 1.187)

Print (str (123) +"456")

Print (bool (1 ))#As long as it is not converted from zeroTrue, 0Is False

Print (int (123.456 ))#Convert to a value after the decimal point

Print (int ("Sandy"))#Cannot be converted, not a basic number requirement

Note: During data type conversion, not all conversions can be successful and exception handling is required.

 

2. Convert numeric values into characters

For example:

Print (ord ("X"))

Print (chr (88 ))

 

Iii. hexadecimal conversion

For example:

Print (hex (200 ))

Print (oct (0, 200 ))

Print (bin (200 ))
