Practical Application
Python String index() Method function is used to extract the suffix or prefix length after or before the target word. The example below displays the total bit length of an instruction coming from AC voltage given information in a string.
Python
# initializing target strings VOLTAGES = ["001101 AC", "0011100 DC", "0011100 AC", "001 DC"] # initializing argument string TYPE = "AC" # initializing bit-length calculator SUM_BITS = 0 for i in VOLTAGES: ch = i if ch[len(ch) - 2] != "D": # extracts the length of bits in string bit_len = ch.index(TYPE) - 1 # adds to total SUM_BITS = SUM_BITS + bit_len print("The total bit length of AC is : ", SUM_BITS) |
Output
The total bit length of AC is : 13
Python String index() Method
Python String index() Method allows a user to find the index of the first occurrence of an existing substring inside a given string in Python.
