python read all lines in a file code example

Example 1: python read file line by line

with open("file.txt") as file_in:
    lines = []
    for line in file_in:
        lines.append(line)

Example 2: python reading lines from a text file

with open(filename) as f:
    content = f.readlines()
# you may also want to remove whitespace characters like `\n` at the end of each line
content = [x.strip() for x in content]

Example 3: read entire content of a file using infile python

#Create a variable for the file name
filename = 'Plates_output_simple.csv' #This is simply a string of text

#Open the file
infile = open(filename, 'r') # 'r' says we are opening the file to read, infile is the opened file object that we will read from

#Store the data from the file in a variable
data = infile.read()

#Print the data in the file
print(data)

#close the file
infile.close()

Example 4: python read lines

f = open("filename")
lines = f.readlines()

Example 5: readlines from file python

f = open("file.txt", 'r')
print(f.readlines())  # array of file lines
