The easiest way to check if a Python string contains a character is to use the in<\/code> operator<\/a>. It returns a Boolean (either True<\/code> or False<\/code>)<\/p>\n\n\n\n

<\/div>\n\n\n\n

Python string contains the character<\/h2>\n\n\n\n

Simple example code.<\/p>\n\n\n\n

s = \"Hello\"\nc = \"H\"\n\nif c in s:\n    print(\"Found!\")\nelse:\n    print(\"Not found!\")\n<\/code><\/pre>\n\n\n\n
Output<\/strong>:<\/p>\n\n\n
\n
\"Python<\/figure><\/div>\n\n\n
Check if the string contains specific characters in a text file<\/p>\n\n\n\n
ser = open(\"hello.txt\", \"rb\")\ns = ser.read(1000) \nif \"developer\" in s:\n  print(\"True\")\nelse:\n  print(\"False\")\nser.close()<\/code><\/pre>\n\n\n\n
Just change ‘rb’ in ‘r’ (or do not put anything, it will be ‘r’ as default). A better way to open a file is this<\/p>\n\n\n\n
with open(\"hello.txt\", \"r\", encoding='utf-8') as ser:\n    s = ser.read(1000) \n    if \"developer\" in s:\n        print(\"True\")\n    else:\n        print(\"False\")<\/code><\/pre>\n\n\n\n
Using a if ... in<\/code> statement. We can do this as follows:<\/p>\n\n\n\n
if 'apples' in 'This string has apples':\n    print('Apples in string')\nelse:\n    print('Apples not in string')\n<\/code><\/pre>\n\n\n\n
<\/div>\n\n\n\n
