I use random.uniform(1,2**100) to produce random floats to the range (0,2**100). Some results are :

>>> random.uniform(1,2**100)
5.9798650563331964e+29
>>> random.uniform(1,2**100)
8.439133849811236e+29
>>> random.uniform(1,2**100)
1.1367823572756921e+30
>>> random.uniform(1,2**100)
6.467828850316163e+29
>>> random.uniform(1,2**100)
6.114089228136624e+29
>>> random.uniform(1,2**100)
5.8262139039159224e+29

I can't get the interpretation of e+29 at the end of each number.

    It is a **very** large number. `1.23e+45` means `1.23 * 10**45` or `123xxx` where `xxx` is 43 zeros. – eumiro Feb 28 '13 at 14:57

It's know as E notation, which is plain text representation of scientific notation.

1.234e+56 means 1.234 * 10**56 or in more human readable form 1.234 × 1056.

"e+number" means 10 to the power of a positive number, in case of a negative number it would be like "e-number".

    If you want to be helpful you should provide examples and a bit more explanation, as the asker is obviously unfamiliar with mathematical notations. – Murphy Feb 12 '18 at 15:02
