python - ame 'leads' 未定义/无法调用 SORT_LEAD(LEADS)

Question

import os, numpy as np
x = ('I', 'II', 'III', 'aVR', 'aVL', 'aVF', 'V1', 'V2', 'V3', 'V4', 'V5', 'V6')
# Check if a variable is a number or represents a number.
def is_number(x):
    try:
        float(x)
        return True
    except (ValueError, TypeError):
        return False

# Check if a variable is an integer or represents an integer.
def is_integer(x):
    if is_number(x):
        return float(x).is_integer()
    else:
        return False

# Check if a variable is a a finite number or represents a finite number.

    if is_number(x):
        return np.isfinite(float(x))
    else:

# (Re)sort leads using the standard order of leads for the standard twelve-lead ECG.
