Printing floats
Scientific notation is a powerful tool for representing numbers, but it can be confusing to handle when trying to print float values. However, we can use the f strings we learned about previously to make sure we get them printed properly every time by using a format specifier. For example, if we wanted to format a variable in an f string as a float, we can use the f format specifier, such as: print(f"{some_variable:f}"). It also takes an operation precision on the float format specifier, for example, print(f"{some_variable:.4f}") would print four decimal places of precision.

Exercise instructions
- Print
float1,float2, andfloat3notice where the jump to scientific notation occurs. - Print
float2andfloat3using the default float format specifier, and notice what happened tofloat3. - Print
float3with the float format specifier and a precision of7.
Hands-on interactive exercise
Have a go at this exercise by completing this sample code.
# Print floats 1, 2, and 3
print(____)
print(____)
print(____)
# Print floats 2 and 3 using the f string formatter
print(f"{____}")
print(f"{____}")
# Print float 3 with a 7 f string precision
print(f"{____}")This exercise is part of the course
