从.txt文件中读取arrays作为数字而不是字符串

Question

I'm using an automatic data acquisition software that exports the data as.txt files. I then imported the file into python (using the pandas package and turning the columns into arrays) but I'm facing a problem. Python can't "read" the data because the automatic data acquisition software exported it into the following number format, and so Python is treating each entry of the array as a string instead of a number:

Is there any way I can "teach" python to read my data? Or to automatically rewrite the entries in the array so they're read as numbers?

Answer 1

You can simply change the comma in the strings with a dot and use float() to parse it.

number = float('7,025985E-36'.replace(',', '.'))

print(number)
print(type(number))

The above code would print:

7.025985e-36
<class 'float'>

Answer 2

You can try this way.

>>> value=str('7,025985e-36')
>>> value2=value.replace(',', '.')
>>> float(value2)
7.025985e-36
