Python: Explicit type conversion

In programming, there are regularly tasks where one type of data needs to be converted to another - for example, when working with forms on websites. Form data always comes in text form, even if the value is a number. Here's how it can be converted:

# str becomes int
number = int('345')
print(number)  # => 345

int() is a function into which a value is passed in order to convert it. The function behaves similarly to arithmetic operations, but does special actions. Here are a few more examples:

value = '0'
# Inside the brackets you can specify a variable
converted_value = int(value)
print(converted_value)  # => 0

# Or a specific value
converted_value2 = int('10')
print(converted_value2)  # => 10

converted_value3 = int(False)
print(converted_value3)  # => 0

converted_value4 = int(True)
print(converted_value4)  # => 1

# If a floating point number is converted
# then all the fractional part is discarded
converted_value5 = int(3.5)
print(converted_value5)  # => 3

Similarly, you can convert data into strings str() and floating point numbers float():

value = str(10)
print(value)  # '10'

value2 = str(True)
print(value2)  # 'True'

value3 = float(5)
print(value3)  # 5.0

Python performs some conversions automatically. For example, in operations where an integer and a floating-point number occur at the same time. Python automatically converts everything to float, a floating-point number:

# Implicitly the code float(3) + 1.2 is executed
value = 3 + 1.2
print(value)  # => 4.2


Output the string 2 times obtained from the number 2.9 (stored in the variable value) and the string times using type conversions and concatenation. To do this, perform two conversions: first to an integer and then to a string

2 times
The exercise doesn't pass checking. What to do? 😶

If you've reached a deadlock it's time to ask your question in the «Discussions». How ask a question correctly:

  • Be sure to attach the test output, without it it's almost impossible to figure out what went wrong, even if you show your code. It's complicated for developers to execute code in their heads, but having a mistake before their eyes most probably will be helpful.
In my environment the code works, but not here 🤨

Tests are designed so that they test the solution in different ways and against different data. Often the solution works with one kind of input data but doesn't work with others. Check the «Tests» tab to figure this out, you can find hints at the error output.

My code is different from the teacher's one 🤔

It's fine. 🙆 One task in programming can be solved in many different ways. If your code passed all tests, it complies with the task conditions.

In some rare cases, the solution may be adjusted to the tests, but this can be seen immediately.

I've read the lessons but nothing is clear 🙄

It's hard to make educational materials that will suit everyone. We do our best but there is always something to improve. If you see a material that is not clear to you, describe the problem in “Discussions”. It will be great if you'll write unclear points in the question form. Usually, we need a few days for corrections.

By the way, you can participate in courses improvement. There is a link below to the lessons course code which you can edit right in your browser.

If you got stuck and don't know what to do, you can ask a question in our community
