In this article we will learn about some of the frequently asked Python programming questions in technical like “how to read text frome another file pythion” Code Answer’s. When creating scripts and web applications, error handling is an important part. If your code lacks error checking code, your program may look very unprofessional and you may be open to security risks. Error handling in Python is simple. An error message with filename, line number and a message describing the error is sent to the browser. This tutorial contains some of the most common error checking methods in Python. Below are some solution about “how to read text frome another file pythion” Code Answer’s.
python read file
xxxxxxxxxx
1
# Basic syntax:
2
with open('/path/to/filename.extension', 'open_mode') as filename:
3
file_data = filename.readlines() # Or filename.read()
4
# Where:
5
# - open imports the file as a file object which then needs to be read
6
# with one of the read options
7
# - readlines() imports each line of the file as an element in a list
8
# - read() imports the file contents as one long new-line-separated
9
# string
10
# - open_mode can be one of:
11
# - "r" = Read which opens a file for reading (error if the file
12
# doesn't exist)
13
# - "a" = Append which opens a file for appending (creates the
14
# file if it doesn't exist)
15
# - "w" = Write which opens a file for writing (creates the file
16
# if it doesn't exist)
17
# - "x" = Create which creates the specified file (returns an error
18
# if the file exists)
19
# Note, "with open() as" is recommended because the file is closed
20
# automatically so you don't have to remember to use file.close()
21
22
# Basic syntax for a delimited file with multiple fields:
23
import csv
24
with open('/path/to/filename.extension', 'open_mode') as filename:
25
file_data = csv.reader(filename, delimiter='delimiter')
26
data_as_list = list(file_data)
27
# Where:
28
# - csv.reader can be used for files that use any delimiter, not just
29
# commas, e.g.: 't', '|', ';', etc. (It's a bit of a misnomer)
30
# - csv.reader() returns a csv.reader object which can be iterated
31
# over, directly converted to a list, and etc.
32
33
# Importing data using Numpy:
34
import numpy as np
35
data = np.loadtxt('/path/to/filename.extension',
36
delimiter=',', # String used to separate values
37
skiprows=2, # Number of rows to skip
38
usecols=[0,2], # Specify which columns to read
39
dtype=str) # The type of the resulting array
40
41
# Importing data using Pandas:
42
import pandas as pd
43
data = pd.read_csv('/path/to/filename.extension',
44
nrows=5, # Number of rows of file to read
45
header=None, # Row number to use as column names
46
sep='t', # Delimiter to use
47
comment='#', # Character to split comments
48
na_values=[""]) # String to recognize as NA/NaN
49
50
# Note, pandas can also import excel files with pd.read_excel()
