Removing elements from a list containing specific characters [duplicate]

by

List comprehensions:

l = ['1', '32', '523', '336']

[ x for x in l if "2" not in x ]

# Returns: ['1', '336']

[ x for x in l if "2" in x ]

# Returns: ['32', '523']

l = ['1', '32', '523', '336']
stringVal = "2"

print(f"{[ x for x in l if stringVal not in x ]}")

# Returns: ['1', '336']

print(f"{[ x for x in l if stringVal in x ]}")

# Returns: ['32', '523']
