Is it possible to write a number in scientific format into a json file without surrounding quotes? I’m using json.dump to save the file. Everything I’ve tried resulted in double quotes around the number. number = 1234.5678 "{:e}".format(number) -> "1.234568e+03" "%e" % number -> "1.234568e+03" f"{d:.4e}" -> "1.2346e+03" The desired output would be: 1.234568e+03 Source: .. I’m running a calculation that outputs a matplotlib plot with a vertical axis scaled with (see image below). ~1e-9-4.998e-1 This is very weird scaling and I’d like to make sure I understand the notation correctly. Does it mean the following? 0.000000001 – 0.4998 = -0.499799999 So far I haven’t been able to successfully google this. ..

I need the first 4 digits after the front 0s in a decimal while also keeping the 0s in the output without getting scientific notation. Would like to take 0.0000000000000000000000634546534 and get 0.00000000000000000000006345 but not 6.345e-23. But would also like to take 231.00942353246 and get 231.009423. Thank you.

I’m polling an API and receiving back numeric values which need to be saved in the DB. The values can look like 0.87199 or sometimes 5.43e-06 or other times 2.2e-11 I want to save them in the DB in their normal form (ie without the exponent). How do I get python to un-scientific convert them? .. With matplotlib-style figures, I’m aware that using: import matplotlib.pyplot plt.ticklabel_format() allows you to set the axis labels into scientific notation or plain style (to suppress scientific notation). This can also be used in some seaborn plots like scatterplot or lineplot: import numpy as np import pandas as pd import seaborn as sns a = pd.DataFrame({"Time":np.repeat(np.arange(1e4,5.1e4,1e4),100), ..

I wanted to ask a quick question about the scientific label next to the colorbar. Is there a way I can change this manually? Basically, I multiplied my data by 10**(-6) which the label next to the colorbar obviously does not factor in. So, I would need to change this automaticallyy generated label from 10**(-6) ..

I have txt files in the format: 6.3894e+02 1.7316e+02 6.6733e+02 1.9942e+02 9.8697e-01 6.4355e+02 1.7514e+02 6.8835e+02 2.0528e+02 9.7908e-01 I want to convert all these values into float as in: 638.94 173.16 667.33 199.42 98.697 643.55 175.14 688.35 205.28 97.908 My code is: import os for i in os.listdir(): if i.endswith(".txt"): with open(i, "r+") as f: content ..
