how to fetch and store integer value inside (...) in a cell in excel to a variable using python-CodePudding

I'm trying to read integer values 10, 12, 2 from the second column of the excel sheet and store it to variables using python.

Using below code I'm able to read the entire data - Parrot(10) whereas i want integer value of 10


# Import pandas
import pandas as pd

# Load csv
df = pd.read_csv("data.csv")

abc = df['Birds'].iloc[0]

CodePudding user response：

Since the question is actually 'how do I extract the number from a mixed string of numbers and letters' you probably want a regex.

import re
cell = "Parrot(10)"
matches = re.search(r"([0-9] )", cell)
number = int(matches.group(1))

There are other approaches, but this is probably the simplest for the dataset in question.

CodePudding user response：

For this specific case you can use list comprehension and join function.

Code:

abc = "Parrot(10)"
number = int("".join([ch for ch in abc if ch.isdigit()]))
print(number)

CodePudding user response：

# Import pandas
import pandas as pd

# Load csv
df = pd.read_csv("data.csv")

word = df['Birds'].iloc[0]
offset = word.find("(")
num = word[offset 1:-1]

This is finding the index of the opening bracket then adding 1 to find the first number then ignoring the closing bracket but only going to -1
