Floating point ranges are not a built-in part of Python. You will need to install the pip module
numpy
to use them.
$ sudo pip install numpy
#!/usr/bin/env python3; import numpy # Begin Main print("Floating point numbers") for d in numpy.arange(1.0, 2.01, 0.1) : print(str(d))
Output
$ python3 Iteration4.py
Traceback (most recent call last):
File "/Users/rich/Desktop/Resources/pureprogrammer/py/examples/Iteration4.py", line 2, in <module>
import numpy
ModuleNotFoundError: No module named 'numpy'
#!/usr/bin/env python3; # Begin Main print("Powers of 2 up to 256!") i = 1 while i <= 256 : print(str(i)) i *= 2
Output
$ python3 Iteration5.py
