I want to make Python repeat simple

I use multiple repetitive sentences separately, but it's a duplicate content... I want to know how to specify multiple of these at once. The repeat statement I use is

    for n in df2.Mag:
        if n >= 0.1 and n < 0.2
        Mag01 += 1

    for n in df2.Mag:
        if n >= 0.2 and n < 0.3
        Mag02 += 1

    for n in df2.Mag:
        if n >= 0.3 and n < 0.4
        Mag03 += 1

...(omitted)

    for n in df2.Mag:
        if n >= 7.9 and n < 8.0
        Mag89 += 1

I made about 80 of them and used them, but I think I can do it without using it 80 times, so I'm opening them to masters For your information, df2 is a csv file, and I want to check how many values of Mag01 to Mag89 are in the df2 file to make a graph later.

Why "about 80"? If you don't have the exact number (e.g., something is not continuous), it might be best to write it down one by one and specify it. -_-;

If everything is continuous and accurate, it can be solved within the for statement by dynamically creating a range (0.6, 0.7...) to compare with the Mag** variable.

Turning the following code to JS

var total = 60;
var mags = [];
for (i=0; i < total; i++) {
  var j = i+6;
  var no = ('0' + j).slice(-2);
  mags["Mag"+no] = (i > i*0.6);
}
console.log(mags);

A total of 60 key-value arrays can be photographed on the console. Please refer to it.

[
  Mag06: false,
  Mag07: true,
  Mag08: true,
  ...
]
