I want to print the length of a float number without trailing zeros using python. examples:
0.001000 >>> I want to get length=5
0.000100 >>> I want to get length=6
0.010000 >>> I want to get length=4
any suggestions?

Converting a float to a str will automatically remove tailing zeros:
numbers = [0.0010000, 0.00000000100, 0.010000]
for number in numbers:
number = '{0:.16f}'.format(number).rstrip("0")
print(f"Converted to String: {str(number)} - Length: {len(str(number))}")
Results:
Converted to String: 0.001 - Length: 5
Converted to String: 0.000000001 - Length: 11
Converted to String: 0.01 - Length: 4

for numbers with more than 4 zeros, it shows '1e-05' Example: (str(float(0.00001))) >>> '1e-05' (str(float(0.000001))) >>> '1e-06' and then it will calculate the length wrong
Try with this:
inp = '0.00100'
len(str(float(inp)))
Output:
This gives the length as 5
All the trailing zeroes will be removed.
